Hi all,

It has been a long time since I configured a Cisco router but have been asked to as I am the only one with any sort of background in this in our organisation.

I have put a Cisco 1921 on our network for once specific server to access an external network via a serial connection. However I have configured this and is on a switch that the server in question is on.

I am accessing the router via a console cable and cannot ping anything on this network however the arp table is being populated by devices on the network.

Sorry if this is an obvious mistake, but I am a bit stumped myself.

Thanks for any advice

The config is -
