### BIG FAT DISCLAIMER
|
|
|
|
|
### The "-i $WAN" literally means packets that came in over the $WAN interface;
|
|
|
|
|
### this WILL NOT MATCH packets sent from the LAN to the WAN address.
|
|
|
|
|
|

|
|
|
### Allow SSH on the WAN interface
|
2005-07-01 18:19:39 +03:00
|
|
|
# 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
|
|
|
|
|
# iptables -t nat -A prerouting_rule -i $WAN -p tcp --dport 22 -j DNAT --to 192.168.1.2
|
|
|
|
|
# iptables -A forwarding_rule -i $WAN -p tcp --dport 22 -d 192.168.1.2 -j ACCEPT
|
|
|
|
|
|
|
|
|
|
### DMZ (should be placed after port forwarding / accept rules)
|
|
|
|
|
# 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
|
