Dobry den,

mam doma Asus Wl500g deluxe. Ve vnitrni siti jsem umistil pocitac na kterem bezi apache2 webserver. Jeho IP=192.168.1.191. Potreboval bych, abych se zvenku mohl dostat pres nejaky port na ten www server. Ted to mam nakonfigurovano tak, ze ted je ten port 30000 a i ten apache posloucha na tomto portu.

Pouzil jsem prikazy:

iptables -t nat -A PREROUTING -p tcp -i vlan1 -d X.X.X.X --dport 30000 -j DNAT --to 192.168.1.191:30000 iptables -I FORWARD 2 -p tcp -i vlan1 -d 192.168.1.191 --dport 30000 -j ACCEPT

X.X.X.X je moje venkovni IP adresa

V tehle konfuguraci m ito nejede. Kdyz napisu http://X.X.X.X:30000 ve venkovni siti (v praci), tak na ten WWW server nevidim. Primo z toho asusu se na ten server dostanu (zkousel sem wgetem stahnout obrazek a jede to na tom portu 30000). Uz nevim jak dal :). prikladam este vypisy z IPTABLES
