More than likely your NAT is misconfigured. 

Here's how I have mine set up (ipnat):
map tun0 -> 0/32 portmap tcp/udp 63000:65535
map tun0 -> 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 (internal client) connects to (gateway), when the data comes back from the remote
server to 63001, NAT remembers that this is actually intended for, and routes accordingly ..

I hope this makes sense to you ..
