internet <--------> Router (As a Bridge) <------------> (PPoe dial-up)WAN 1- Peplink - LAN (10.133.0.1)<---------->(10.133.0.2)-Ext.Int - Firewall <------> Local Network
My customer want used PPTP VPN on Firewall behind Peplink, so i try configure and test. But no success.
So, How configure step this situation on Peplink ?
In this scenario, you will have to configure inbound access (port forwarding) in the Peplink Balance.
Generally PPTP needs the following information in the Balance:
IP Protocol=TCP, TCP Port number=1723 <- Used by PPTP control path
IP Protocol=GRE (value 47) <- Used by PPTP data path
Therefore, you will need to create two configurations in the Balance. Network > Inbound Access (Port forwarding) > Services > Add Service
IP Protocol = TCP Single Port 1723 / Inbound IP Address(es) <- you set up the public IP address of the WAN(s) / Included Server(s) <- it should be the IP of your Firewall (10.133.0.2)
IP Protocol = Protocol Number 47 / Inbound IP Address(es) <- the same as the above. / Included Server(s) <- the same as the above.
