Hi smalkeric.

It was not an error afterall. It turned out the it was supposed to do that.

The Pix501 was used as a vpn tunnel access to the network but was not the main router. The inside host I was pinging did not have a route to the network I was on as its main route pointed to the main router

10.5.10.1 main router

10.5.10.4 vpn router

After a "route add 172.26.1.0 mask 255.255.255.0 10.5.10.4 -d" on the inside host I got a reply on my pings.

Thanks anyway.
