My customer has a PIX 501 at the HQ. The remote users use the Cisco VPN client to establish the VPN which has been up for almost 2 years. Now they want to setup a site-to-site vpn for one of their remote sites. The new firewall for the remote site is an ASA-5505 but I just can't get it to work.
I've successfully ping both sides (not with this config). I've issued the show ipsec sa and show isakmp but no tunnels are established. I've also used debug crypto ipsec 7, debug crypto isakmp 7 and ping w.x.y.z and ping 126.96.36.199... but the tunnel won't even establish (debug has no output). The remote users can still use the vpn client to connect to the pix without any issues. Please help.
The configs are attached.
