Googletalk behind a packet inspecting firewall.

[mpierik]

I always used to connect to googletalk on port 80 since we have a rather strict firewall at school and it blocks the default port. After some research using the official googletalk client on a windows laptop it appeared that gtalk was accepting connections on port 80.
This worked for me untill recently they installed a new firewall. This firewall inspects the packets that pass through and if it receives a packet on port 443 that isnt a proper SSL packet it drops it.
Since they installed this firewall i havent been able to connect to gtalk. People using the official client are still able to connect tho.
adium passes the following error message to me in a dialog when i try to connect:

Code: Select all

mpierik@gmail.com (GTalk) : Gaim error SSL Handshake Failed

Is there anything i can do about this? i can still use the new function in gmail to talk to my contacts but i'd rather use adium ofcourse.
If there's any additional information that can help resolve this problem please let me know and i will try to get it.

I don't know if this is connected, but i've been having the same problem for some time now, but I only use the built in software firewall in Tiger. i've also been seeing "Gaim Error: read error".

Is there noone with a solution to this problem? When i use tcpdump i see adium is trying to send traffic over port 443 but the official googletalk client sticks to port 80.
