Hi,
Please, if posting Logs, do not post any Log info after the line "Binary Images for iChat"
I post the Above green bit at the bottom of all my Posts in the iChat Forums and the iSight one.
I even mentioned in my last post that this info is not needed.
Airport Base Station.
Launch the Airport Utility in Applications/Utilities
Click on your device in the left hand column then use the Manual Configure button.
Change to the Internet icon.
If, at the Bottom of this pane you are "Sharing" and IP" then the device is dong DHCP. There will also be three tabs across the top of the pane.
Select the NAT one.
In here make sure Port Mapping Protocol is Enabled.
You may have set this device up to join the existing Network of the Modem (It will say Bridge (Off) Mode and have no NAT tab- and not need the Pot Mapping thing)
What Make of DSL Modem ?
Does it Route (Issue IP addresses) ?
Does this modem have DOS or SPI ?
Cable Modem and Linksys.
The Cable Modem is not likely to Route.
The Linksys Router may also handle the ISP Login via PPPoE
Linksys
Access the Set up Pages.
In the Administration page make sure UPnP (Universal Plug and Play) is Enabled.
In Applications and Games disable any Port Forwarding set up and also any Port Triggering.
Also make sure DMZ is not enabled.
If the device has a Security tab go there.
If, (Again), it has a Firewall listed as the top items Disable this as it contains DOS and SPI features.
There is also a line about Accepting (or Blocking) Anonymous "Requests". This is PING Blocking. It needs to be set so that these PINGS are allowed. (if it Reads "Block" then Disable it.)
As I mentioned before, DOS is Threshold Based.
Someone or a Server has to be sending you data fast enough to trigger the reaction of the DOS filter.
It may happen with a HD quality Video from a Fast server.
For some people they may only see it in 4 way Video Chats when they are Host (All Data is sent to them from the other three), but it really depends on the Speed and Pic size (bigger pic = More data per frame) that is being sent.

There is something about the ports in this LOG
1.546835 @/SourceCache/VideoConference/VideoConference-422.36/SIP/Transport.c:338 type=2 (00000000/0)
[INVITE
sip:user@sip:25335 SIP/2.0
This port should read 16402
Via: SIP/2.0/UDP rip:16402;branch=z9hG4bK1d4109eb4408aa6d
Max-Forwards: 70
To: 0 <sip:user@sip:25335>
SO should this port
From: u0 <sip:user@rip:16402>;tag=203415462
Call-ID: 1e011409d9a97de-1140-11e0-b29e-edb87ace4012@rip
CSeq: 1 INVITE
Contact: <sip:user@rip:16402> ;isfocus
User-Agent: Viceroy 1.4
Content-Type: application/sdp
Content-Length: 706
The ID points to this Log being an Incoming call as does the isfocus line.
There appears to be two things going on.
1) The connection is getting cut (most likely in a router somewhere)
2) The ports are Random ports and not the usual iChat Ports (Suggests they are not open)
Concentrate of the first of these as the Connection is being made essentially.
