Re: [H] Netopia Cayman 3341 GW modem
http://www.netopia.com/support/hardware/technotes/CQG_042.html Tharin, I have stumbled across this netopia process for disabling the modem's nat when a router will be behind the modem. Can I follow it to try again to set this modem up? The only question about this process is that it requires me to use public lan address (of the router?). This is step 10b. Can I use the router's address (192.168.2.1) as my public address even though it is really another private address on a different subnet than the modem (192.168.1.254)? If so, I think this 3341 just may work! Best, Duncan At 19:45 12/09/2007 -0800, you wrote: Hrmm I've installed many of these Netopia ADSL gateways for business grade dsl customers in my area. The Cayman units require a special key file be installed to unlock certain capabilities. I don't know whether yours might be locked for SBC region or what kind of settings you will have access to. The main thing with configuring a DSL modem of any sort is to be sure you are using the proper VPI and VCI settings. Most SBC modems come with a setting of 0/35. I think Bellsouth uses 8/35. Ask Bell's tech support if you need to confirm it. Encapsulation should be PPPOE. Multiplexing should be set to LLC. A google search turned up this doc for configuring the device for Bridging. http://www.netopia.com/support/technotes/hardware/CQG_020.html When did this come into the picture I thought you had a Westell modem and Dlink router??? -Tharin O.

Re: [H] Netopia Cayman 3341 GW modem
The Netopia units are meant to be a gateway/router so it will likely have its own Firewall, DHCP server, and NAT features enabled. You need to disable these things if you want to use this gateway as just a simple bridged modem. What you mentioned about the router halfway working when you switch the ethernet cable from the WAN to LAN plug means your Netopia gateway is not properly configured yet. There is no way you could have the modem configured for bridging if you are connecting to the internet when the router is connected through its LAN port instead of its WAN plug. Assuming you are using PPPoE authentication to establish your DSL connection, the intellinet router would not be able to perform this function over one of its LAN ports. This scenario tells me you still have this turned on in the Netopia unit. Turn it off!! You could always forget about the intellinet router and just use the Netopia gateway since it is a NAT router also! Call Netopia. My experiences speaking with them on the phone has been a pleasant one. SBC wasn't much help at all when dealing with this equipment so I just talked to Netopia directly. They emailed me the 'feature key' files that were necessary to unlock some of the menus/settings in their equipment. I don't recall ever having to pay a fee for phone support. a couple more helpful links :) http://www.netopia.com/support/hardware/3341.html http://www.netopia.com/corp/contact_us.html
Re: [H] Netopia Cayman 3341 GW modem
Eh.. no not really or at least not all of it. A 'public ip' is supposed to be the internet routable ip assigned by your provider. This is the address you would see when you go to something like http://www.whatismyip.com I think this doc is for people who still require PPPoE but are somehow are assigned a block of static ip addresses once connected. This is not a situation I've seen in practice in the real world but I guess it is possible. See what you can do about disabling NAT and DHCP and then configure the modem as bridge. Another guide on enabling bridge mode http://www.seidata.com/bridge Disabling NAT (might not be necessary, but you can try it if all else fails) http://www.netopia.com/support/hardware/technotes/CQG_015.html DHSinclair [EMAIL PROTECTED] wrote: http://www.netopia.com/support/hardware/technotes/CQG_042.html Tharin, I have stumbled across this netopia process for disabling the modem's nat when a router will be behind the modem.

You need to disable these things if you want to use this gateway as just a simple bridged modem. Yes, I realize this. Have been reading/studying the CQG's from netopia. There do not seem to be a way to implement it. I can disable DHCP. When I try to disable the NAT f/w, it seems to go into the ozone and never come back until it gets a RTFS (little pushbutton!). I do have setup instructions for enabling RFC-1483 Bridged Ethernet vcc1, but only if ISP has given me a static IP - NO! Is dynamic. What might be RFC-1483 Routed IP? What you mentioned about the router halfway working when you switch the ethernet cable from the WAN to LAN plug means your Netopia gateway is not properly configured yet. No, did not mean the Intellinet router (box2) was halfway working. It flat will not talk to the 3341 (box1) yet. I gave up with the router for now. Per the router's setup screens it is all setup correctly for the home LAN and ready to try and connect to the modem. It does not. Because the router (box2) is x.y.2.1 and the modem is x.y.1.254, I feel this is the main trouble between the two. If I have read your previous study docs properly. :) There is no way you could have the modem configured for bridging if you are connecting to the internet when the router is connected through its LAN port instead of its WAN plug. Correct. When the modem is connected to the router's WAN port, there is no internet at all. Confirmed. Assuming you are using PPPoE authentication to establish your DSL connection, the intellinet router would not be able to perform this function over one of its LAN ports. This scenario tells me you still have this turned on in the Netopia unit. Turn it off!! Turn what off? The PPPoE auth in the modem? You could always forget about the intellinet router and just use the Netopia gateway since it is a NAT router also! Yes, this is exactly as I left it all yesterday. The Intellinet router is only supplying its' switch ports to connect to the 3341. I have also disabled the DHCP server in the Intellinet router so that the DHCP server in the modem assigns the PCs addys on its' subnet (x.y.1.1 - x.y.1.16) Call Netopia. My experiences speaking with them on the phone has been a pleasant one. SBC wasn't much help at all when dealing with this equipment so I just talked to Netopia directly. They emailed me the 'feature key' files that were necessary to unlock some of the menus/settings in their equipment. I don't recall ever having to pay a fee for phone support. Will do! I need to ask them about firmware anyway. Most of the CQG's relate to a firmware level of 7.0+. This modem is at 6.3.0r7, which is or is not appropriate for a 3341 depending on which CQG I am studying(?). I would really prefer to use a firmware update as a real last resort! Thanks for the links below.am there right now as I write this!

I think this doc is for people who still require PPPoE but are somehow are assigned a block of static ip addresses once connected. This is not a situation I've seen in practice in the real world but I guess it is possible. OK, thank you. Understand. I am now back on solid ground. Yes, this is how I read the CQG for PPPoE. Everything reads well until step 10b! We do not get an address block from Bellsouth. Another dead end. See what you can do about disabling NAT and DHCP and then configure the modem as bridge. This I will attempt again. Q - If I can get NAT and DHCP disabled in the modem, can I believe that its' router function is also disabled? I have done this, but the modem and router still will not connect and play nice! Another guide on enabling bridge mode http://www.seidata.com/bridge I'll study this link for the bridge of the modem. So far it only seems to go to partial-bridge only. Disabling NAT (might not be necessary, but you can try it if all else fails) http://www.netopia.com/support/hardware/technotes/CQG_015.html If I do not disable NAT at the modem, I will have a double-NAT situation. The Intellinel router provides NAT w/SPI by default.
