I cannot connect to my PPTP server from WAN side. It simply stalls and disconnect me, though connecting to StrongVPN PPTP server presents no problem at all. Previously I can connect to the PPTP server fine.
The problem is, I can’t connect to my pptp server from every connection. So, it’s like I can connect to my pptp server from hotel A, but not from hotel B. Those locations that I can’t connect, I can connect to the mikrotik just fine via winbox.
I thought the access point does not allow vpn, but I can connect to StrongVPN pptp without any problem.
Please advise on how should I troubleshoot this problem.
