Hi, I am wanting to change the source address of outgoing packets that have a src port of 53. I have tried /sbin/iptables -A POSTROUTING -p tcp -t nat -o bond0 --sport 53 -j SNAT --to-source 192.168.0.1:53 This doesnt work, it seems to be that you cant SNAT to a port the same as the original src port because /sbin/iptables -A POSTROUTING -p tcp -t nat -o bond0 --sport 53 -j SNAT --to-source 192.168.0.1 /sbin/iptables -A POSTROUTING -p tcp -t nat -o bond0 --sport 53 -j SNAT --to-source 192.168.0.1:52 both works, but obviously not the same results as I wanted because the src port is also changed. Is there any other way to do what I am wanting?? TIA
