I am having an issue ping the far side of a Cisco router from an HP2626 VLAN_ID 2 (172.168.70.x). The default VLAN_ID 1 on the 2626 has an IP of 204.68.155.44. I am able to ping from the 172.168.70.x (VLAN_ID 2) to all other 204.68.155.x IPs. This includes 204.68.155.x addresses connected directly to the ProCurve 2626 and ones which are connected to another switch.

Our router to the public side has an internal interface of 204.68.155.248, which I am able to ping from 172.168.70.x (VLAN_ID 2). However, I cannot ping the far side of the Cisco (63.138.237.40).

Does anyone know why this would be?

I see you have both a default gateway as well as IP routing enabled - from memory the software doesn't allow both to be enabled at the same time even though they both seem to be present in the config.

Try doing a "show ip route" and see what info comes back. It should tell you whether IP routing is enabled / disabled and what default gateway is defined.

Workaround I've used before is to setup a static route to mirror the default gateway function and leave IP routing enabled.

Perhaps NAT rules on your router are preventing the traffic from being routed back?

That was the issue. I took out the entry for the default gateway in the initial setup and entered a static route on the ProCurve for 0.0.0.0 0.0.0.0 204.68.155.0 This did the trick. I am very surprised that it does not give you some type of error when IP routing is enabled that it overrides the default gateway.

Anyway, thanks for your answer. It was very helpful.
