winsock IP correct for useing Port Forwarding?

[fgp123]

im trying to connect to an internal Computer though a router remotely with winsock. The cod ei have works fine within the LAN, but imm trying to connect to it form the outside.

I have set up the Router to set port 80 with the internal ip address of the maching i wish to connect to.

im then useing

mdiMain.winsocks.RemoteHost = "999.999.999.999/80"

(First 4 sets of digits changed for obvious security reasons posting them on the web.)

But i have no joy. Im new tro useing winsocks and prt forwarding (tunneling) so im not 100% sure i ahve everythign set up right.

Any ideas? can anyone run though a check list of things i should have done to set this up?

You are using the external IP address of the router? The one from your ISP?

Post your setup like what router you are using, what ports you are trying to use ect.

Give your friend the external IP address, and port forwarding will work. Don't give the one on your computer that the router forwards it to.

im useing a ZyXel prestige 600 router. I have set the port forwarding up as..

Ports From: 80 Ports To: 80...........IP 192.168.0.4
Ports From: 21 Ports To: 21...........IP 192.168.0.4

IP address is Internal Lan address of machine i wish to forward to, 80 and 21 are the HTTP and FTP ports used (i just asumed these would be the ones i would need to use for useing winsock?)

I got my works external IP addres from the PortForwaring.com web site (it shows you what your external IP address is.)

I then use the same line of code i use for talking to the machine while within
Then LAN.

mdiMain.winsocks.RemoteHost = "999.999.999.999/80"

Where 999.999.999.999 is the external IP address of the company LAN and useing the /80 to forward on port 80 which should forward to the 192.168.0.4 IP inside the lan.

But im getting no connection.

You're getting no connection because you don't forward 80 and 21 unless you want to host a web server and an ftp server. You have to forward the port that your program is using. Know that whole business of LocalPort for winsock connections?
