I hope you are fine.In fact i have an issue about a firewall installation.The firewall is behind a speedtouch adsl modem in brigded mode so the outside interface ip address is the one the isp gave me.I created a default route pointing to that outside interface i also configure a pat on the outside interface for users on the lan to access the internet.Surprisingly I was able to ping the next hop address of my isp and the host on the lan from the pix firewall but the host on the lan can not ping the outside interface or access the internet.What do you think is the issue?

NB I explicitely permitted icmp on the outside interface of the pix firewall so i should be able to ping it from the lan.

There is no access-list blocking any traffic.

Your answers will be highly appreciated

Pretty hard w/o a config, but I did notice something that sounds fishy.

I created a default route pointing to that outside interface

Your default route should point to the ISP's address, not your local IP on the PIX.
