I've tried to setup PPTP on my DD-WRT, I can connect to the router from my Windows XP via PPTP from the LAN side to my public IP on the WAN side, traceroute confirms the extra hop once I connected, obviously, this is not much practical use, however, it verify the login process and the connection does work.
I then took my PC to a public library, I can connect and login from the public library to my router via PPTP, however, once the connection is being made, I cannot do anything other than pinging my VPN default gateway, which is the PC itself, I cannot ping other PC on my internal network, I cannot browse the internet.
Once thing I noticed is that my internal network use IP range (192.168.1.0/24) and the public library network uses IP range (192.168.0.0/23), obviously the public library uses NAT too, and the 2 IP address range overlaps each other, so I assume this is at least one of the problem, so my question is: is the only solution to change my internal network IP range to something like 192.168.198.0/24 and hope it does not overlap with whatever network IP subnet I will be using in the future?
Are there other obvious things that I should pay attention to PPTP setup on DD-WRT?作者: 角色 時間: 2011-5-10 06:03
Haha！ This is because the firmware installed in the public library. We had a long discussion in the past in EPC forum.
If you want to break the public library, you have to open openvpn with 443 TCP port.
