Hi, I just brought up a Cisco 2620 router on my external network. It's in the same network as my border router.
I can ping to my gateway router but can't get out from there.
Here's my config.
Thanks!

Greetings:
Your configuration is incomplete. First, your serial0/0 interface is "shutdown", so no traffic can pass. Should this be "IP unnumbered" or did the ISP give you an address for that interface?
Second, the "IP default gateway" command will not work. You need a default route.
If the ISP gave you a 206.217.239.x address for serial0/0, you will look something like this.
interface Serial0/0
ip address 206.217.239.x (netmask)
no shutdown
ip route 0.0.0.0 0.0.0.0 206.217.239.1
I am just speculating on the configuration above based on experience. If you can indicate the IP addresses the ISP provided for each interface, I could be more specific. If you feel uncomfortable putting those in this forum, you will need to open a case.
Thanks...Steve

The default route did the trick.
I'm not using my serial port. From my border router, I cannot to a hub and one of the hub ports is populated by this 2620, going into its Ethernet port.
I took out the default-gateway command.
Thanks!

Is this the configuration of your border router, or of the 2600? When you say you can "ping the default gateway", but cannot get out, can you get out to the internet on the default gateway? If so, it sounds like a routing or possibly an ARP issue. Or you can possibly clear arp on the default router.
