 Subject:  Cable modem issue with m0n0wall
 Date:  Tue, 03 Aug 2004 16:15:04 -0500
Hi,

Comcast is in the process of taking over my broadband service from 
Insight Communications.

Since switching to a Comcast address range, I have been having frequent 
problems with my Internet connection. In the log (the SW error should be 
irrelavent--they are trying to put motorala firmware in my Linksys 
modem) below is a typical sequence that repeats over and over while 
connected via m0n0wall...then, at 15:32, I connected a sacrificial XP 
machine directly to the cable modem at which point the modem properly 
synched up immediately. On the XP machine, the network interface had the 
following values:
IP            68.x.y.z
subnet      255.255.252.0
Gateway  68.x.a.b (within same subnet as IP)
DHCP      172.30.58.34
DNS        68.57.q.r
                68.57.q.r+1

I am guessing that the IP address of the DHCP server is giving me 
trouble. Any ideas? What else do I need to provide to complete this 
picture? (There is no route to 172.x.x.x in m0n0wall routing table.)

Same issues using a Linksys BEFCMU10 modem and a Motorala SB5100 modem.

One more question: Is there a way to force m0n0wall to release and renew 
DHCP on the WAN interface?

Thank you for any help.
