### BIG FAT DISCLAIMER
|
|
## The "-i $WAN" is used to match packets that come in via the $WAN interface.
|
|
## it WILL NOT MATCH packets sent from the $WAN ip address -- you won't be able
|
|
## to see the effects from within the LAN.
|
|
|
|
### Open port to WAN
|
|
## -- This allows port 22 to be answered by (dropbear on) the router
|
|
# iptables -t nat -A prerouting_rule -i $WAN -p tcp --dport 22 -j ACCEPT
|
|
# iptables -A input_rule -i $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_rule -i $WAN -p tcp --dport 8080 -j DNAT --to 192.168.1.2:80
|
|
# iptables -A forwarding_rule -i $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_rule -i $WAN -j DNAT --to 192.168.1.2
|
|
# iptables -A forwarding_rule -i $WAN -d 192.168.1.2 -j ACCEPT
