Re: static ipv4 NAT

Hi Sadiq,

Sorry but I was too quick to respond.

yes you are right, I can have a NAT statement for the port to be
translated and the other stream will go through with no natting. My
testing still requires to test NAT transversal so I will need to
translate the source ip in both cases but only PAT on one stream.

I'll try to configure later today.

Thnks
Rich
