Port forwarding

You can forward port 80 and 443 to Ant Media Server, so you don’t have to use ports.

You can use following iptables commands

sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 5080
sudo iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-port 5443

To make it permanent, edit

vi /etc/ufw/before.rules

In the beginning of the file, find

*filter

Add above

*nat
:PREROUTING ACCEPT [0:0]
-A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 5080
-A PREROUTING -p tcp --dport 443 -j REDIRECT --to-port 5443
COMMIT

Restart ufw firewall

ufw disable
ufw enable
