IP Routing problem

[darthgarlic]

I have a Cisco 2621 (172.30.1.50) attached to a network (172.30.1.0) the firewall is the gateway (172.30.1.1) and I cant ping anything in the real word by IP or by name. As the gateway and the Ethernet port are on the same network I dont think I need a routing statement in the Gateway/firewall. Can someone tell me what I am doing wrong?

To reach the Internet, you would of course need to configure default gateway on the router, otherwise, the router wouldn't know where to route the traffic to.

To configure default gateway on the router, and you mention that firewall is the gateway to the Internet, you would need to configure the following:

ip route 0.0.0.0 0.0.0.0 172.30.1.1

Further to that, you would also need to check that the firewall is configured for NAT/PAT, access-list/policy to allow the traffic through towards the internet.
