Re: [pfSense Support] LAN / WAN disconnections - Motorola Surfboard SB5101 Cable Modem?
Thanks Raj The modems web interface is, as you suggest, present at 192.168.100.1. The modem is being used in a transparent mode (bridging?) as the static IP is assigned on rl1. So far as I can tell it is not using 0.0 on the WAN side, it is using 3 digit numbers for the a.b.c.d IP address.

You have 192.168.0.4 on your lan, but for some reason your cable modem also sends arp replies for that ip. One possible reson is that your ISP might be using 192.168.0.0 network for the HFC side of cable modem. Try browsing to 192.168.100.1 and check if you get the cable modem web interface. From here you can check the ip address assigned to your modem. (I am typing from my memory, so I might be wroing about the cable modem web interface ip) If your ISP is using that ip range for HFC network, you will have to change your lan ip addressing. raj - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Can I presume that means you have checked and confirmed there are no similar messages in your System Logs? I no longer use this setup, my 5101 is sitting in my basement collecting dust. However, I would have noticed both the error _and_ the issue. Other suggestions. Check your netmask on both interfaces. I know WAN will be DHCP, but it's worth seeing what the ISP is sending you and confirming that it makes sense. Seeing as you are on a HUGE layer 2 broadcast domain, it's entirely possible that there's some joker out there sending out gratuitous arps - not sure offhand how to stop that in pfsense (I know how to do it in the OS, but that won't help you here). You can check the arp tables on the firewall (at any time, but likely most useful after it stops working) by doing an 'arp -an' from the command prompt. --Bill - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[pfSense Support] LAN / WAN disconnections - Motorola Surfboard SB5101 Cable Modem?
Hi I am finding one of my pfsense boxes is losing its internal connection between the LAN and WAN. Happens maybe once a week or longer... The WAN seems to be OK, as I recall I can ping the Internet still and ping / access the Motorola config page at 192.168.100.1 There are no error messages in the system log at the time of occurrence. Running top in ssh or on the monitor looks much the same with no process dominating anything, although the web response may be longer. The WAN is cable via a Motorola Surfboard SB5101. A colleague of mine is also using the same pfSense and modem - and having the same issues. We are both finding frequent logged messages of this ilk: kernel: arp: 192.168.0.4 is on rl2 but got reply from 00:00:cd:1c:06:8c on rl1 In my case the cards are all of rl variety, his are xl. Reloading the filters does not fix it. Rebooting usually does although sometimes I seem to need to power cycle the modem also. When tested the Modem has remained up as I can connect up an alternative NIC appropriately configured with the static IP. It is a pain when offsite as one cannot remotely trigger a reboot to gain system access. How can I progress identifying the issue from here? Kind regards David
Re: [pfSense Support] LAN / WAN disconnections - Motorola Surfboard SB5101 Cable Modem?
Which interface is rl1..ditto for rl2. Also, any chance that both sides of the firewall are plugged into the same switch? I've had the same modem you mention running on pfsense without any problems, so this smells of a different issue to me. --Bill On 5/16/07, Tortise [EMAIL PROTECTED] wrote: Hi I am finding one of my pfsense boxes is losing its internal connection between the LAN and WAN.
