5506-x wan via dhcp

Richard Langly — Fri, 21 Feb 2020 14:57:29 GMT

I'm trying to setup a 5506-x but unable to reach the internet. When I do a 'show ip', the outside network has 'unassigned' for an ip address. I was hoping someone could go through my config to tell me where I am going wrong. If I can get one interface going (1/1), then I think I can duplicate the rest of my interfaces to do the same.

Any help much appreciated.

Your outside interface is set as dhcp. The question is, do you have an dhcp service to provide ip for this interface?

I'd recommend you set an static IP instead. Dhcp for outside interface can create problem for management and VPN.

Yes, I have a modem (SB6121) and the outside interface has always connected to Comcast ISP via DHCP.

I see but if you are receiving "unassigned" this means then that the DHCP is not working. Have tested with a PC or something?

Well, seems I just needed to restart the modem. It's working now. This 5506 is a new one from the previous 5506 I had (but was an early model and had an issue where it would only last about 18 months before the components went bad).
