Ignacio,

Hmmm, it does look there is a problem. When the NAT-T port is changed in 
the Site Configuration, it should only effect the destination port used 
when the client sends traffic to the gateway. It really doesn't make 
sense to change the source port because we expect this to be translated 
by a NAT gateway anyhow.

Please try the following build and let me know if it helps out at all.
