PPTP server on multi-wan doesn't allow outside connections

[mfil67]

Hello,

I need again a help from this fantastic community :)

the current internal network where I've installed pfSense is structured this way: 3 different subnets (LAN1, LAN2, LAN3) + 2 different WAN (WAN1, WAN2).
Using pfSense I've managed to load balance the WAN output of LAN1 to WAN1 and LAN2/3 to WAN2, everything is working properly.

Now I need to set up PPTP VPN server on pfSense and I've correctly set it up, but there are some issues with it that I'm not able to fix.

1. The PPTP connection works correctly for internal use, but it doesn't allow me to connect to the outside from a PPTP connection. I've even added the specific gateway to be used though yet I cannot get out of the internal network. This is really weird as I've tried on another smaller network with a single WAN and pfSense is correctly allowing the client connected through PPTP to surf the web

2. Is there any way to specify on the PPTP server provided by pfSense the subnet LAN that should be used (either LAN1/LAN2/LAN3) by the DHCP to assign the IP?  Let's say that the user1 should get the IP from the DHCP set on the LAN1 while the user2 should get the IP from the DHCP set on the LAN2. Is this possible in any way?

Thank you very much for your help, as always :)

Kind regards
