PPTP Problem

I am facing problem in PPTP Connection. I have configured PPTP Server in my MK and successfully connecting to my Office MK Router, I can ping all the switches, PC & devices of my Office Network even I can SSH and Telnet them, but the problem with web service.. whenever I am trying to open the webpage of any device its show connecting to nnn.nnn.nnn.nnn(IP address of device) but never open it. If I try to open any SSL secure page of my device then its show SSL Certificate but don’t proceed further.
