Home LAN with Linux Firewall forwarding the internet connections and two clients - Client 1 = Win 98; Client 2 = Windows XP. My homelinux is Fedora Core 3 by the way...
I use RealVNC (Free Edition 4.1.1).
Problem: I canīt connect to one of my clients (XP) through the Internet although everything looks well configured. The message VNC returns after some time trying to connect is: Connection Timed Out.
Here is my Vnc, Client and Router/Firewall configs so that we can see if everything is tightened up and should be running.
VNC: Is waiting connections on a specific port wich I will call "vnc port".
Client: I entered the windows Firewall Exception rules and created two exception rules wich permits incoming connections to the "vnc port" (both of them. Client and HTTP). This client has an assigned IP wich I will call "client assigned IP".
Router/Firewall: The server has a Firewall rule wich permits incoming connections through "vnc port" and those incoming pakcets should be "DNAT-ted" to the "client assigned IP":"vnc port".
/sbin/iptables -A FORWARD -j ACCEPT -i $wanic -p tcp --dport "vnc port"
/sbin/iptables -t nat -A PREROUTING -i $wanic -p tcp --dport "vnc port" -j DNAT --to-destination "client assigned IP":"vnc port"
Ok thatīs it. Why isnīt it running. Maybe here someone can see something I forgot.
Last thing: Iīd like to know what is the right way to connect with the client or browser to VNC on a SPECIFIC PORT. I used for both: "Router/Firewall IP":"vnc port". So it would look like something like this: 18.104.22.168:12 (totally random IP/port). And beyond this, The Firewall should be redirecting the connection to the client and port specified.
