ASA FIREWALL ISSUE

pl.mailloux — Fri, 11 Oct 2013 16:39:29 GMT

On SITE-A my PC's IP adress come directly from the ASA 1.1.1.x

On SITE-B we use a router behind the firewall so my PC's adress are : 192.168.1.x

I can ping from SITE-B to SITE-A without any problem.

I cannot ping from SITE-A to SITE-B.

There is my 2 firewalls config.

Thanks
