Hello everyone, I need some help with a project of mine. Basically, I’m about to move into a new apartment where the internet is managed by the landlord. To protect my internal network, I purchased an ASUS RT-AX88U Pro so I can run a VPN at the root of my personal network. The VPN is working flawlessly; however, I’m having trouble with the port forwarding feature. I’ve installed Asuswrt-Merlin 3004.388.8_4 and followed this documentation to set everything up: However, even after following the guide step-by-step, none of the ports seem to be open. Here are the iptables commands I used: # For port 55730 iptables -I FORWARD -i tun1 -p udp -d 192.168.50.36 --dport 55730 -j ACCEPT iptables -I FORWARD -i tun1 -p tcp -d 192.168.50.36 --dport 55730 -j ACCEPT iptables -t nat -I PREROUTING -i tun1 -p tcp --dport 55730 -j DNAT --to-destination 192.168.50.36 iptables -t nat -I PREROUTING -i tun1 -p udp --dport 55730 -j DNAT --to-destination 192.168.50.36 # For port 62980 iptables -I FORWARD -i tun1 -p udp -d 192.168.50.36 --dport 62980 -j ACCEPT iptables -I FORWARD -i tun1 -p tcp -d 192.168.50.36 --dport 62980 -j ACCEPT iptables -t nat -I PREROUTING -i tun1 -p tcp --dport 62980 -j DNAT --to-destination 192.168.50.36 iptables -t nat -I PREROUTING -i tun1 -p udp --dport 62980 -j DNAT --to-destination 192.168.50.36 # For port 56241 iptables -I FORWARD -i tun1 -p udp -d 192.168.50.36 --dport 56241 -j ACCEPT iptables -I FORWARD -i tun1 -p tcp -d 192.168.50.36 --dport 56241 -j ACCEPT iptables -t nat -I PREROUTING -i tun1 -p tcp --dport 56241 -j DNAT --to-destination 192.168.50.36 iptables -t nat -I PREROUTING -i tun1 -p udp --dport 56241 -j DNAT --to-destination 192.168.50.36 # For port 55798 iptables -I FORWARD -i tun1 -p udp -d 192.168.50.36 --dport 55798 -j ACCEPT iptables -I FORWARD -i tun1 -p tcp -d 192.168.50.36 --dport 55798 -j ACCEPT iptables -t nat -I PREROUTING -i tun1 -p tcp --dport 55798 -j DNAT --to-destination 192.168.50.36 iptables -t nat -I PREROUTING -i tun1 -p udp --dport 55798 -j DNAT --to-destination 192.168.50.36 Despite running these commands, none of the ports appear to be open when I test them externally. however they seems to be open in the router interface ( see screenshot ) thanks you for your help :)
