HI,
I started here just to see some pics
Several general things struck me.
The talk about going to the WAN setting page (on the way to set Port Forwarding) but show a Pic about the Firewall.
This firewall if On does SPI which can interfere with iChat.
I presume you have this Off ?
Also it shows Ping Blocking is On and ichat will need it Off.
iChat sends Pings to confirm where the Visible part of the Invite went to is the same place that is responding.
The Pics have something called UPnP Media server and it would be quite useful to see the setting in here.
Linksys devices mentions UPnP in two places and only one of these works effectively and I am curious about what has to be set here.
Below that you have EzQoS Bandwidth management and also in the pic under the line about Virtual Servers it shows another access to something else labelled QoS.
Now QoS is about managing the bandwidth for certain apps.
It is mostly associated with VoIP (voice over the Internet/IP Phones)
These apps tend to use SIP (Session Initiation Protocol) and so does iChat.
These may be linked to something called Application Layer Gateways (ALGs)
I would turn these OFF if you can.
The Port Triggering may give you another options as it works for Multiple computers.
It can be difficult to set it up for multiple applications though (depending what UPnP is used for currently)
However you will not be able to Screen Share if you use this method due to iChat using a random port.
Sorry that this info is a bit generic but without actual pics and testing it is a little difficult to be that precise.
