I'm using shorewall 4.5.5.3 on a Debian distribution. I have tried the following rule in /etc/shorewall/masq : eth0:y.y.y.y - x.x.x.x:5060 udp 5061 But on the remote system I still see the traffic coming from x.x.x.x:5061 instead of x.x.x.x:5060. I even tried to change x.x.x.x with 1.1.1.1 but I still see the traffic coming from x.x.x.x The rule gets loaded by shorewall but for some reasons it doesn't works : 11:24:48 Compiling /etc/shorewall/masq... 11:24:48 Masq record "eth0:y.y.y.y - x.x.x.x:5060 udp 5061" Compiled Any ideas ?
