Hello, i created a vpn thunnel between site A and Site B. The thunnel shows to be active but i am not able to ping from either side to the other. The ip address schemes are different. Any ideas what i am missing. Site A is using a sonic firewall for vpn and Site B is using a cisco router.

any ideas what to do next would be great help.
Thanks in advance.
