Re: [WISPA] Private vs Public addresses for end-users
I haven't had any issues with 1-1 and I've been doing it for over 8 years. Primary firewall is a Checkpoint so that may be part of the reason I haven't had issues. Running most of my broadband customers through Mikrotik though - only had that for about 3 years, but still haven't had any problems. I'm sure someday, somewhere I will. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of rabbtux rabbtux Sent: Wednesday, January 30, 2008 1:33 PM To: WISPA General List Subject: Re: [WISPA] Private vs Public addresses for end-users Have you had any vpn problems or such for 1-1 NAT customers?

Re: [WISPA] Private vs Public addresses for end-users
In your case I could see where that's an issue. We used to manage IP's on a spreadsheet, but now we do it with a web based system. Each installer has a temp IP they can assign at the customer location, get online, grab an open IP, and assign it - no big deal for us. Hey, not saying you're wrong at all - just expressing my side as well :-) hehe - I think the guy that asked about this is definately getting his money's worth! -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ryan Langseth Sent: Monday, January 28, 2008 7:10 PM To: WISPA General List Subject: Re: [WISPA] Private vs Public addresses for end-users My thoughts got ahead of my fingers,, it was supposed to say bigger and more profitable. I am looking at it from my standpoint, we have 2000+ customers, 48 POPs and yes, all static IP addresses (a mix of internet routable and rfc1918). We have 2 full time installers and 2-3 CSRs on during business hours. Now, in order to assign an IP address the tech has to call in and get one from the CSRs, that can take awhile especially when we are busy. Assigning and managing IPs is done with a BFS (Big %#ing Spreadsheet), I am guessing you currently use the same method. Now we could assign the IP address on the work order, but then you have to make sure it gets used, or marked as free if it is a no-go, this is more difficult with more people. Also since we have multiple CSRs we have to have the BFS shared, that causes numerous time delays when saving, making changes and dealing with conflicts. Luckily I hardly ever have to deal with the BFS, or IP assignment. But I do believe it can be better Rather than looking at how well it works now, take a look at how it will work in the future.

Any radio worth its salt that does true bridging would also have a bridging table that is accessible via SNMP or HTML screen scraping. One of our in-house programs polls all the AP's (we're a Canopy outfit, but same principles apply to most Ethernet-based gear) and saves the MAC addresses to a database, where I match the MACs to the subscriber's radio and back to their account. It's usefulness is most apparent when a customer wonders why their connection is lousy and we can see that they've either got 1) their radio plugged into a switch instead of a router and we can see all their computers, or 2) their computer is doing one of those change-my-mac-every-10-seconds network attack things. Our central DHCP server logs which router the requests come from as well, helping us to narrow down which section of the network to search in the case that the MAC doesn't show up in any of the radios.

Re: [WISPA] Private vs Public addresses for end-users
First one must define public address. Meaning public IPs used belonging to the upstream ISP or the WISP owning their own block of public IPs. Owning your own block, you must ask... Is it worth the technical admin headache to manage them, and is the expertise there to do it. And is the benefit there, if the expertise was. The primary benefit for a small ISP is just to be portable between upstrewam providers, any time you want to be. Usually the answer is its not worth owning your own, unless you have scaled large enough to justify a /19 or higher. However, using an upstream's public IPs, costs nothing in most cases. And they do the painful management of it. Using private IPs, is also making it portable between providers, because its very quick and easy to create a new NAT rule to map the private addresses to any new Upstream's shared public IP. So the real question come up as... Is it a benefit to your subscribers to use public IPs, different than every other subscriber. Some VPN protocols require static IPs. Some corporate firewalling requires static IPs. Some VOIP services require public static IPs. Web servers and Mail servers require static IP. Access the subscriber from a remore PC for remote desoktop requires public static IP. Sharing IPs, will mean that if one customer gets blacklisted for sending SPAM, so will all your other subscribers. It is definately possible to offer services using private IPs to the end users, many residential ISPs have chosen to do so. But doing so, does restrict the services that your subscribers will be able to do. But that may be a benefit. If you are selling $9.99 broadband, you won't want them to ahve the ability to host mail and web servers. IF you are competing against commodity monopolies, you may want the added features to distinguish your self. Step 1 is defining what services that you'd like your subscribers to be able to do. And then you make an IP allocation method that enables that.

Re: [WISPA] Private vs Public addresses for end-users
The biggest cost in using Static IP is after support. Thinks liek Linksys routers are notorious for loosing their configurations. When teh configuration is lost, your on the phone for an hour walking your customer through how to enter the IP back in. MOst commodity routers default to DHCP, so if it loses its config, rebooting will still get it a working IP with out a phone call for reconfiguration. However, we only use Public Static IPs. We typically charge more for our service and justify the higher charge because of added benefits such as Static IP benefits. We are willing to spend the time.

Re: [WISPA] Private vs Public addresses for end-users
If the default for most routers is DHCP, then give it a private block and then D-NAT all port 80 traffic to one of your servers and give them a spash-page that says...Your router lost its' configuration. Here are instructions of how to reset it. Don't forget, the default for most routers' wireless is wide-open. If you lock them out by default...it is in both of your interests to get it set back up and secure. I'll spend the extra 15-20 minutes to walk them through a configuration so their neighbor has to pay for a connection.

Re: [WISPA] Private vs Public addresses for end-users
My thoughts got ahead of my fingers,, it was supposed to say bigger and more profitable. I am looking at it from my standpoint, we have 2000+ customers, 48 POPs and yes, all static IP addresses (a mix of internet routable and rfc1918). We have 2 full time installers and 2-3 CSRs on during business hours. Now, in order to assign an IP address the tech has to call in and get one from the CSRs, that can take awhile especially when we are busy. Assigning and managing IPs is done with a BFS (Big %#ing Spreadsheet), I am guessing you currently use the same method. Now we could assign the IP address on the work order, but then you have to make sure it gets used, or marked as free if it is a no-go, this is more difficult with more people. Also since we have multiple CSRs we have to have the BFS shared, that causes numerous time delays when saving, making changes and dealing with conflicts. Luckily I hardly ever have to deal with the BFS, or IP assignment. But I do believe it can be better Rather than looking at how well it works now, take a look at how it will work in the future. If you are ok with what you see, continue how you want. I am only expressing my opinion and will not feel bad if you do not agree with it. ;) Ryan On Jan 28, 2008, at 5:16 PM, Jason Hensley wrote: Not sure where the 10+ minutes per install addition for a static IP comes into play.

Re: [WISPA] Private vs Public addresses for end-users
Ryan, Have you considered using DHCP to manage manually assigned IP addresses? It offers the best of both worlds. The IPs are statically mapped to customers, yet the allocations are managed on the server side, eliminating the concern about ongoing maintenance (lost client settings). Additionally, duplicate IP allocation is prevented. ted On Mon, 28 Jan 2008, Ryan Langseth wrote: My thoughts got ahead of my fingers,, it was supposed to say bigger and more profitable.

Re: [WISPA] Private vs Public addresses for end-users
We are looking into doing DHCP Option 82 for our NMS DHCP subnet for our CPE devices. If I am understanding this correctly, through this option I will be able to designate the IP address(es) that are going to be allocated behind that CPE device. This way I will only have to track MAC address of customer through my inventory and billing system. Through DHCP server, we will be able to determine which IP address is linked to specific CPE devices. Am I dreaming here?

Re: [WISPA] Private vs Public addresses for end-users
If you have access to the DHCP server then it should be pretty trivial to migrate. Your current lease file will show all of the IPs and their associated MAC addresses. All you need to do is build a static lease file from this information. I am finally migrating from a static IP to DHCP with static IP assignment. With newer equipment I have the radio act as a router and assign the IP to the radio since I know the radio MAC at provisioning time for the customer. For my older equipment (mostly CB3s) I have used some custom scripting on my mikrotik APs to get this to work. I assign temporary DHCPs out of a separate ip pool with a 30s lease, I then use a captive portal on that pool of IPs. They are redirected to a web page which displays a message stating that their equipment has changed and please wait 30 seconds for us to update our records. While they are staring at the page. I have a script that logs into the MT AP, check the last-ip field on the /interface wireless registration stats page and matches that mac-address with the radio mac-address in my provisioning system. Then set the /ip dhcp-server lease record for the correct IP address. The webpage has a 30 second redirect to their original destination and all is good. After 3 years of service, I finally decided that I was tired of the customer calling in after every router reset or router upgrade. It is also nice to be able to tell the customer to just hit the reset button on the router after their 12 year old has hosed the router trying to get their xbox 360 set up.

Re: [WISPA] Private vs Public addresses for end-users
Yes but there are some security concerns with DHCP when sharing wireless sectors. To prevent requires tracking MAC addressess, which is one more headache to track. Sure if you are doing true 802.11 CPE, no problem, the link uses the MAC of the CPE that you already know, but when supporting true bridging, it means discovering teh MAC of the customer provided Home Router.
