NAT and UDP

Hi there

I'm having problems with certains online games when doing NAT. I've enabled the NAT debugging and got this:

2d04h: NAT: Allocated Port for 10.0.17.51 -> 213.113.x.x: wanted 1477 got 1477

2d04h: NAT: i: udp (10.0.17.51, 1477) -> (213.115.y.y, 14567) [26958]

2d04h: NAT: s=10.0.17.51->213.113.x.x, d=213.115.y.y [26958]

2d04h: NAT*: i: udp (10.0.17.51, 1477) -> (213.115.y.y, 14567) [26960]

2d04h: NAT*: s=10.0.17.51->213.113.x.x, d=213.115.y.y [26960]

2d04h: NAT*: i: udp (10.0.17.51, 1477) -> (213.115.y.y, 14567) [26962]

2d04h: NAT*: s=10.0.17.51->213.113.x.x, d=213.115.y.y [26962]

2d04h: NAT: Allocated Port for 10.0.17.51 -> 213.113.x.x: wanted 1478 got 1478

where 10.0.17.51 is my internal ip from which I try to connect, 213.113.x.x is my external IP and 213.115.y.y is the IP of the server.

Isn't the following line weird?

2d04h: NAT: Allocated Port for 10.0.17.51 -> 213.113.x.x: wanted 1477 got 1477

shouldn't it be 213.115.y.y instead of 213.113.x.x? (the server ip instead of my external)

Does anyone know what can be wrong?

Thanks in advance!

Re: NAT and UDP

Stefan,

The debug output is simply showing you the translation that is happening. The lines with the s=x and d=x syntax is showing you the source and destination IP addresses. Hope this helps!
