PPTP Server....IP Address binding

I’m using a MT 433 OS v3.27 connected to 2 carriers so I have 2 public IP’s on different subnets. I’m running a dial-up VPN server on the MT. However the PPTP server is being bound only to IP1.

So if if try to connect to IP1 I get a successful VPN connection. I’m able to browse into the network successfully and all.
But if I try to do PPTP on IP2 there is no connection (I can see the incoming PPTP connection while torching)

Is there any way to bind the PPTP server to IP2 instead of IP1?

Thanks

seems like you should add connections marks for interface with IP2 and then route answers to that packets via interface2
