We have a site to site VPN established between two Sonicwall TZ170 firewalls and a Cisco 3030 concentrator.
S1 is a Sonicwall Tz170w standard : Addresses behind this are 192.168.22.x and 192.168.23.x
S2 is a Sonicwall Tz170 enhanced : Addresses behind this are 192.168.0.x thru 192.168.9.x
C is a Cicsco 3030 : Addresses behind this are 10.x
The tunnels are up and we know that they are working because PCs behind S1 are able to access private resources behind C. (using a variety of ports) However, PCs in S2 are not able to access servers or PCs behind S1.
Anyone know why S1 PCs can access C servers, but S2 PCs can't ping or VNC into S1 Pcs?
