Use any port really. It probably doesn’t really matter so long as it’s above 1024. Let’s say you choose port 5000.
I’d recommend using a second ip address and forward all traffic on ip2:80 to ip1:5000. That way you can get around any firewall restrictions on your network.
If you want more details about adding a second ip address and adding a NAT to your iptables to forward traffic from port 80 on ip2 to port 5000 on ip1, I can share my notes with you.
