Smoothwall Express 3 - Unable to get an ip from ISP (dhcp cable modem)


[Log in to get rid of this advertisement]
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).

Thanks

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.
