THIS IS THE ONLY PORTION OF THE firewall.user FILE THAT I CHANGED.
### Open port to WAN
## -- This allows port 22 to be answered by (dropbear on) the router
iptables -t nat -A prerouting_wan -p tcp --dport 22 -j ACCEPT
iptables -A input_wan -p tcp --dport 22 -j ACCEPT
### Port forwarding
## -- This forwards port 80 on the WAN to port 80 on 192.168.1.4
iptables -t nat -A prerouting_wan -p tcp --dport 80 -j DNAT --to 192.168.1.4
iptables -A forwarding_wan -p tcp --dport 80 -d 192.168.1.4 -j ACCEPT
