However, if the servers on Site B do not know where to route the traffic for the VPN user, it will go out through the default gateway and therefore never reach the VPN user. Routing If the Sonicwall performs SNAT for any traffic going from Site A to Site B (possibly due to overlapping subnets), then traffic from the vpn user towards the servers at B will work and the reverse will also work, because the original address has been replaced by the SNAT with the address of the Sonicwall, which performs the reverse translation, too.There are a number of possible reasons for this.
