Google talk not connecting with transparent proxy settings.

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Whenever we login to gtlak without giving manual proxy setting in connection 
tab we get the error. With manual settings it goes through.


What is the expected output? What do you see instead?
It should have got connected. It fails giving error"Connection to the Google 
Talk service was blocked"


What version of the product are you using? On what operating system?
it is beta version. 1.0.0.104 and is same on Windows 7 & 8 flavors of Windows. 



Please provide any additional information below.
We have deployed Websense Proxy in our network recently. To configure proxy 
settings we are using WCCP on our Cisco ASA firewall. So all our http, https & 
ftp traffic is getting re-directed to proxy. basically all traffic on 80 & 443. 
Now with this settings we do not need to set proxy IP manually in end-user 
browsers but whenever we try logging in to Gtalk it fails . It connects when we 
define proxy setting in Gtalk connection settings.
But manually defining this is not feasible as we have many roaming users who 
are not technically sound hence once they are out of company network they face 
challenged in putting back the proxy settings to default.


We checked the logs and got to know that it is trying to connect directly over 
port 5222 using JABBER Protocol. Hence we edited WCCP access list and now we 
have allowed tcp/5222 traffic to goto proxy. But still we are facing same 
challenge in connecting to GTALK.

Further troubleshooting we got below logs on proxy. Hope you can understand it 
and help us in getting this resolved.
