vpn, voip and port related question
My ISP has blocked -or- start tracing perticular packet type (Voip), so, I can't use
sip/h323 voip service any longer. I need to check which port are blocked by my ISP.
so, I have 2 questions.
1. what is the way , I can check which port still remain open by my ISP
2. Is there any perticular port used by VPN technology? Is this possible to
restrict use of VPN (blocking vpn port) by ISP ?
This is very urgent.
