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]
