We've got 2 SSG5 devices, connecting site A and B together via site to site VPN. The VPN is working fine, machines can talk to each other.
Site A = 192.168.10.0/24
Site B = 192.168.100.0/24
The actual problem is that any traffic from Site B appears to come out via the Tunnel interface and not the actual IP of the machine sending the data.
We should also mention, that the Interface that the tunnel is bound to is doing NAT, because we also do let external clients access machines on Site B using MIP's.
Example:
If Host B at Site B has an IP of 192.168.100.5 and is speaking to Host A at Site A, the source addresses of the traffic coming from Site B are translating to the IP address of the tunnel interface (which is 192.168.100.1).
This does not occur the other way around, only when Site B talks to Site A
Any suggestions? or Extra neede details?
