m0n0wall Forum - PPTP server IP address as LAN IP

Hi,

I just need to use LAN ip address (192.168.0.158) as PPTP server IP address (192.168.0.158); and the remote ip network in different network segment (10.10.1.96/28). When I define the PPTP server IP address as LAN IP address, It is complain that

The following input errors were detected:

* The specified server address is equal to the LAN interface address.

I can add WAN IP address (which is public IP address) with no issue; and pptp works fine.

But my requirement is:
Have 3 interfaces -
LAN - Local Network (192.168.0.0/24)
WAN - Internet
OPT1 - LAN2 (192.168.100.0/24)

Only authenticated users have LAN2 access where they coming from LAN segment using pptp.

Is this possible or as it complains we can't add LAN IP address for pptp..? I have add different LAN IP address but I can't even telnet to the 1723 port...!

Thanks
