[tproxy] tproxy 4.1 squid 3.1.19 not working for yahoo mail

[Ming-Ching Tiew]

I am using linux kernel 3.2.21 ( also tested a few other versions ). 


Basically I could get basic tproxy working by following this instruction.

http://wiki.squid-cache.org/Features/Tproxy4

Everything I follow strictly except rp_filter I have to set to zero. 

Then I could visit some website and it seems tproxy is working.

However I have problem with one or two website, yahoo mail in particular, 

which is not working well. I wonder if this is the forum which I could post 

some follow details in troubleshooting the problem ? 


The symptom of the problem is slow in login and impossible to logout from
yahoo mail. The browser complains of zero byte received.
