mikrotik pptp server only on one ip adress

Hi to all..

As far as I know, if you turn on pptp server, it is active on all interfaces and all ip addresses.
But I have multiple public addresses, and I would like to pptp be active only on 1 address, and on other to forward GRE and TCP 1723 to some other internal pptp server.
How can I do this? Is it even possible?

Thank you…

You can control which IP addresses the RouterOS PPTP server will respond on using input filters in IP Filters. Likewise you can use NAT to forward PPTP requests made to other IP addresses to a second internal PPTP server.
