Can't Ping past gateway

Shaun McCloud

OK, I am having a grand old time on this issue.

I can not seem to ping past my gateway on my outside interface no matter what I change. (well if I change the device to a pc then I can ping out)      

I can not ping the ASA from the outside either. It is as if the default route is not working but I don't know a way to double check it, other then verify it in the config. The ARP table also does not show any outside address, so any help you can offer would be great!

Hi,

Looking at your "outside" interface configuration it would seem to me that you are using the Network/Subnet Address as the gateway IP address for the default route.

It seems to me that if your ASAs IP address is .89 then your gateway should be .90 as .88 is the Network/Subnet address and the .91 is the Broadcast Address.

Network x.x.x.88/30

  • x.x.x.88 = Network Address
  • x.x.x.89 = ASA Address
  • x.x.x.90 = Gateway Address
  • x.x.x.91 = Broadcast Address

Or is the gateway perhaps .89 and the ASA should be using .90?

So can you try to change the default route configuration and then see if everything works and if you can see something in the ARP of the "outside" interface.

route Outside 0.0.0.0 0.0.0.0 x.x.x.90 1
