Hello and thanks for your post,

I didn't mention in my post that my VPN server is multihomed and its also
the DC, DNS, DHCP for the domain. Is also important to mention that the WAN
interface in my VPN server is a simple NIC connected by Ethernet to an ADSL
modem, so my WAN interface has an IP of 192.168.1.2 and uses 192.168.1.254 as
the default gateway which is the intranet face of the ADSL modem.

Yesterday I disable the WAN interface (secondary NIC) and configure the RRAS
to use the Intranet interface (primary NIC), which has an IP address of
192.168.1.1, and the PPTP ports were available!!!! I configured the VPN by
PPTP just fine.

The issue is that I want to use the primary NIC only for DNS, DHCP etc for
the intranet clients and the secondary NIC only for VPN users, but when I try
to configure the VPN with this NIC no PPTP ports are available!!! Only L2TP
ports.

I think the problem is with the IP address for my WAN interface, however I’m
not 100% sure, if you have any suggestions or articles please send it to me.

Best regards
