AFAIK if you do not specify listen directive poptop will bind to all
available interfaces.
[root@edward ~]# netstat -na|grep 1723
tcp 0 0 0.0.0.0:1723 0.0.0.0:*
LISTEN
Anyway this is not the problem.
The problem is that if the PPTP client connects to the ip-aliased address
the PPTP server should use the same address for the outbound communication with
the target server.
I am pretty sure it is not implemented in the current version of pptp.
I wonder if it can be done with iptables or routing?
