windowsupdate and ssl_bump

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

 

We are using a 3.4.8 squid Proxy in intercept mode via wccp.

Squid intercepts HTTP and HTTPS via ssl_bump.

All is working fine except that Windows Machines can’t do a Windows Update.

It is not working at all giving an error  80072F8F

with HTTPS redirection disabled all work fine.

 

Someone knows how to maintain the SSL interception with a functional Windows Update ?

 

Thanks

 

Josep
