Thank you everybody,

I've attached the monoweall status page and answered some mails all
together in order to be more efficient:

I'm connecting from a windows laptop in a network. The IP is
DHCP assigned.

The x.x.x.x/28 is hardcoded in monowall since it only supports 16 PPTP
simultaneus connections. The 28 Is not the netmask is a way to define a
range of IPs.

Monowall Documentation says about server address: "This can be an unused
IP on your LAN ..." and, as an example, defines Server Address
"" and Remote Address Range "".

About PPTP connection and the /32 subnet in the PPTP client: "It should
have an IP address that is in the range you defined for the PPTP Server.
It should also have the subnet of and it will be using
itself as the default gateway. Just live with it; it is how it works."

I defined "form any to any" LAN and WAN rules but it does not work.
