Can't share files or video chat

Question

Hi, I've been having problems with sharing files with buddies and video chatting.
When I send a file to a friend or when they send one to me, I get this response: "Communications with the AIM proxy timed out. Try again."
When I try to video chat with my friend and vice versa, I get this response: "There was a communication error during your chat. Did not receive a response from ... "
I looked through some topics, but I haven't found a solution yet. I changed my Port settings to 443; audio/video bandwidth at 500kbps; quicktime streaming at 1.5kbps. No luck. I have no idea what's going on, so I would appreciate any help.
Thanks!

Hi,
How to Access
This page will tell you near the top, but below most of the adverts and the Line that Reads "Do Not Skip This Step", what IP to type in to a Web Browser and then What User name/word to use and what the default password is.
This is of course if you have not altered the IP the Router's set up pages are on and have not changed the Default User Name and Password.
Only use this access info and Don't bother with the Port Forwarding Instructions (I have linked you to the ones for AIMTalk which is not enough ports)
What to do in the Set up Pages
From this Emulator you will see UPnP is in the Advanced tab and then Advanced Network menu item on the left.
Make sure this is Enabled.
Just below that for this device you will see the WAN Ping Blocking setting.
In this case you Tick the Box to Enable response. As iChat sends a Ping you want to Enable this.
Use the "Save Setting" button at the top
Then go to this page in the Advanced Tab across the top and Firewall down the side.
Disable the SPI setting.
This tries to inspect every piece of data that comes to your Network.
Basically with modern internet Speeds the device cannot process Video Stream data enough and will interpret that as an attack and drop the one port that data stream is on (to "protect" the connection as a whole).
Save Settings on this page.
At the bottom of this page is what is called Application Layer Gateway(s) (ALG)
If iChat does not work.
There is one for SIP which is a protocol that iChat uses to Connect A/V chats.
It should be enabled by Default but if you still have issues with iChat Video or Audio Chats then Disable this item.
Looking it up in the support pages held on the device did not say if it forces SIP to port 5060 (iChat in iChat 3 and 5 uses port 16402) and you may need to Disable this item

SIP
Allows devices and applications using VoIP (Voice over IP) to communicate across NAT. Some VoIP applications and devices have the ability to discover NAT devices and work around them. This ALG may interfere with the operation of such devices. If you are having trouble making VoIP calls, try turning this ALG off.
