Smoothwall Express 3 - Unable to get an ip from ISP (dhcp cable modem)
Hello everyone
Here is my setup:
cable modem -> smoothwall -> switch -> comps
The smoothwall is set to green+red
green is on 192.168.0.1
So I enable the dhcp server of my smoothwall and the computers on the switch can talk to each others and I can connect to the web-interface of my smoothwall. The problem is that I can't access internet (the smoothwall itself cannot ping nor does the cable modem shows any sign of activity).
I think that the problem is in Networking tab of the web-interface under Interface. The red interface should be set to DHCP with hostname as the name of the smoothwall right? I get a dynamic IP from my ISP. It seems like the cable modem doesn't want to give the external ip adress to my smoothwall... what to do? (The cable modem is connected via ethernet to the red NIC).

Powerdown your smoothwall and modem. Wait for about 15 seconds. Fire up the modem, wait for the lights to settle then powerup smoothwall. That works for me.

i have the exact same issue and turning it on and off again doesn't fix this issue... my DD-WRT router seems to work fine.. it grabs the ip address from virgin media and starts working... but when i plug the cable modem in to the RED Ethernet port on my smoothwall router my smoothwall can't seem to DHCP and pick up its ip address.... the GREEN port is working fine with no issues....

Have you tried watching the boot process for any messages that might give a clue as to what is going on. You could also try re-assigning the network cards just to check that they are working.
Thanks Nexus for the quick reply. Happy holidays!!!
I watch the boot process as carefully as I can but obviously it's very fast. However, I think the problem always comes out in something like "waiting for DHCP" but it waited too long and didn't get an IP so it doesn't get an IP (the RED connection).
I've tried changing the RED and GREEN. I've tried the reinstall at least 10 times.
My GREEN network can talk to each other and I can access the smoothwall web interface by my browser and my GREEN (by doing ifconfig eth# command) I can see that the GREEN network card is getting an IP, but I do the same ifconfig for the RED and it doesn't have an IP address and doesn't say "UP" (but the GREEN says "UP").
I'm pretty sure that my RED is not working... (even though I have it set up as DHCP on the RED because Verizon FiOS does dynamic IP).
PLEASE FOR THE LOVE OF GOD HELP ME. I CAN'T GET ANY SLEEP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
