### 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 8080 on the WAN to port 80 on 192.168.1.2
 | 
						|
# iptables -t nat -A prerouting_wan -p tcp --dport 8080 -j DNAT --to 192.168.1.2:80
 | 
						|
# iptables        -A forwarding_wan -p tcp --dport 80 -d 192.168.1.2 -j ACCEPT
 | 
						|
 | 
						|
### DMZ
 | 
						|
## -- Connections to ports not handled above will be forwarded to 192.168.1.2
 | 
						|
# iptables -t nat -A prerouting_wan -j DNAT --to 192.168.1.2
