Help on allowing others to connect to me

[Jonathan August]

Hello fellow VNC Users!

This is my first time posting as I have just recently downloaded the
program.

My question is as follows:

Using my computer I can connect to my other friend's computer as she has
VNC. However, if she tries to connect to me, she is not able. I know that I
am behind a firewall, but I am telling her to use "IP":5900 as the port. She
still cannot connect to me.

Is there anyway to fix this?

Also, when I roll my mouse over my VNC tray icon, it shows my IP. However,
when I received my confirmation email from VNC Mailing List it showed a
different IP (I also used this one to try and have my friend connect and it
failed). Is there a reason for this?

Thank you all!

Jonathan
