More than likely your NAT is misconfigured.
Here's how I have mine set up (ipnat):
map tun0 192.168.56.0/24 -> 0/32 portmap tcp/udp 63000:65535
map tun0 192.168.56.0/24 -> 0/32
Basically what this says is:
- All internal traffic will be routed between 63000-65535
- All outgoing connections from internal machines will be temporarily
translated. Meaning, if 192.168.56.5:3456 (internal client) connects to
192.168.56.2:63001 (gateway), when the data comes back from the remote
server to 63001, NAT remembers that this is actually intended for
192.168.56.5:3456, and routes accordingly ..
I hope this makes sense to you ..
