Port forwarding problems

Log into it and check, may be it is not necessary, I don't know. It has to have a web interface with settings.

I was entered int ADSL modem through web application, but this modem's default setting is to accept all packets through in both directions. After that I added iptables commands:

Code:

iptables -A FORWARD -i eth0 -o eth1 --sport 80 --dport 80 -j ACCEPT

For this command I get error:
unknow arg '--sport'
unknow arg '--dport'

Do you have any other ideas?

Ok, may be it is my mistake.

Try to use you command, but

iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to-destination 5.2.2.231
