hi list

my buddie is trying to get his webserver working behind his debian router. this is what i gave him (we tried once with --dport and once with --dports):

iptables -t nat -A PREROUTING -i $WAN_IFACE -p tcp -m multiport --dports 22,80 -j DNAT --to-destination $SERVER

i'm not able to connect to his webserver with http://his_ip/
what am i doing false? got any ideas?

thanx
eric

well make sure apache is first installed correctly and loads up just fine.. Try doing an apache -S to make sure it loads fine

secondly theres 2 things needing to be done

first need to forward the port

iptables -t nat -A PREROUTING -d externalip -p tcp --dport 80 -j DNAT --to webserverip:80

and also make sure the port you want is opened in your FORWARD as well

iptables -A FORWARD -p tcp --dport 80 -j ACCEPT

will prob have to change around those cmds a lil bit to suit your needs, but hopefully that gets you on the right track.
