I've installed haproxy via entware so that I can tunnel both openvpn (running on router) and a separate locally hosted https server through port 443 of my router. I need to tunnel openvpn over port 443 because some WiFis block access to non standard ports and I need https over 443 so that the website viewer doesn't have to finagle with non-standard port access.

I've manually added an iptables rule to open up port 443 on my router.

Why does this work:
iptables -I INPUT 2 -p tcp -m state --state NEW --dport 443 -j ACCEPT
while this doesn't:
iptables -I INPUT 2 -p tcp --dport 443 -j ACCEPT
Is it informative that I still can't get the remote users IP on my https server's access log?
