skype behind proxy server failed saving any data files
My Skype Application was connected behind the proxy server of pFsense with squidguard
the target rules list was allow as Default Access [all]
To connect Skype need to set the proxy server IP Address under internet explorer -> Tools -> Internet Options -> Connections -> LAN Settings then put check Proxy Server enter the IP Addres to Address and port is 3128 then put check Bypass proxy server for lcoal address then Ok after that i open my Skype Apps in my Desktop PC it appeared username and password and i already logged.
the pproblem is about saving of any files is failed but sending any files was working properly.
my questions is why i cant save files is there any specific port that i need to open it in pfsense firewall or i need to have regular expressions rules under squid proxy
