portforwarding

portforwarding

[Eric Marchionni]

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.
