Hi, I am trying to forward port 1723 for VPN PPTP connection to our internal server. However the connections are not going through when trying to connect through the WAN port, i.e from the internet.

I have set up the port forwarding in the virtual server settings. Are their any other settings I need to change to get this to work?

Our VPN used to work with our old Draytek Vigor 2820 router which we have just replaced with The TP-Link one.

details:
TP-Link Load Balance router TL-ER5120 v2.0
Firmware: 1.0.8 Build 20140212 Rel.36037

Any help would be appreciated

Hi Panda,
I managed to test our VPN from my home internet connection and had no issues connecting. It looks like the router is getting confused when testing the VPN from within the LAN connection. This may be due to our leased line connection which means the WAN port ip address is the same as our public ip address. I think it is getting confused with the VPN connection coming from the LAN and pointing at the WAN port address so is not forwarding the packets correctly.

However as it is working from the outside this is not a major issue, and will just add a bit more work for when we want to test it. May be worth keeping in mind if other people have similar issues.
