My Video chat is not working with messages.

Question

When someone tries to send me an invite for a video chat the green light shows up but I do not receive and invitation window to accept it.
I am using an aim account on messages and my server settings are api.oscar.aol.com, port 443, and use SSL is checked.
In connection doctor is says my router type is port restricted and that "This computer's network setup includes one or more devices that are not fully compatible with audio and video chatting. I am not sure if this is the reason my video chat is not working.
If anyone can help me please let me know.

Hi,
Most routers can be accessed via  Web Browser.
The IP shown in System Preferences > Network > Advanced Button > TCP/IP tab in the "Router IP" box is generally the one to use.
You also tend to need a User ID and Password.
Apple Base Stations are different in that they have an App in the Utilities folder that accesses the set up screens.
Your router can have different methods of opening the ports.
Port Forwarding
This tends to be the oldest of the methods.
Essentially you point a port to an IP (computer) to allow it.
A collection of ports may need to be entered one by one.
Once set up, only that computer can use those ports.
Port Triggering
This cuts down the number of ports set to be Open as it involves "listening" ports that then open further ports
iChat/Messages needs some ports to be open all the time and you set these a bit like Port Forwarding but with listing the IP to send the data to.
The A/V side can have a listening port (port 5678 for the Visible part of the Invite)
The advantage is that multiple computers can use the same ports.
DMZ (Demilitarised Zone)
This is an ON or Off setting (Enable/Disable)
It opens all the port (65535 of them) to one IP (i.e only one computer can use this.)
It is sort of like Port Forwarding Extreme
UPnP (Universal Plug 'n' Play)
A setting that allows the App to tell the router which ports to open.
This means the router can carry on doing DHCP and multiple computer can use the ports involved.
Where these setting are varies at least as much as there are manufacturers.
This is  Linksys Port Forwarding (the arrows above the pic show the Others  (it does not show DMZ)
