Hello everyone, I'm writing a program that deals with SIP packets. I have a MagicJack phone running on my old laptop, but I am developing on another computer. I need somehow to redirect/retransmit packets which go to the laptop so that they would also go to my computer on which I am developing. I'm guessing that I can do it with a firewall rule, but my knowledge with iptables is limited. Is this even possible? If so, then what firewall rule will take all the packets and retransmit/duplicate/forward them to an additional IP on the network?
