asa5505 can't ping both ways.

lon21

Guys I have a lab running which has a host connected to the 2.1 range but I'm not able to ping my outside interface. I understand that the asa blocks ping both ways but surely I would be able to ping my default gateway of the asa which is 10.0.0.1.

You need to enable icmp inspection. By default, there's typically a default set of inspection rules that applies to all interfaces, however, I can't see any in your config.

I know, when I use asdm the ping does not go through. But if I use a http request it works just find.

In which case how can you test connectivity through a firewall ?

Guys the solution is to place a access list on both end.


Thanks
