2824 Routing issues
Hello, I am trying to use the 2824 as a router, but not having much luck. The config is attached. There are only 2 relevant VLANS; 1 & 90. I have port 1 set up on VLAN 90 and only one machine attached (192.168.90.100). From this machine I can ping either interface (192.168.90.1 & 143.246.0.72) but can not ping anything else on the 143.246.0.0/17 network. Can someone please tell me what I am missing?
Thanks - John
Well, I tried to attach the config, but it would not post, so here is the config inline:
Running configuration:

Re: 2824 Routing issues
Hi,
Are you sure the computers in 143.246.0.0/17 are able to find its way back to your 192.168.90.0/24 network?
SInce you're not using any dyanmic routing protocol you'll have to manually specify that the 192.168.90.0/24 network is routed via 143.246.0.72, probably from the machine that is acting gateway for the other clients (143.246.0.50?)
edit: also, i think that ip default-gateway is only used when the switch is not in routing mode, when its routing you'll have to use ip route 0.0.0.0 0.0.0.0 143.246.0.50 for the default gateway.

Re: 2824 Routing issues
Hi John
What is the default gateway for the devices in Vlan 1 ?
For now I am assuming it is 143.246.0.50
Does the device 143.246.0.50 have a route pointing to network 192.168.90.0/24 via 143.246.0.72 ? If nto it should have one :).

Re: 2824 Routing issues
Oh, DUH. What was I thinking??! Yes, that is most likely the issue. You are both correct. The 0.50 machine is the gateway. I will make changes to get a path back to VLAN 90 and I am sure that will fix the issue.
Thanks to you both for answering my question. - John
