I am running m0n0wall version 1.2b8 on a PC-Engines Wrap 1E-2. I have
encountered a bug in the software that I believe was originally reported in
this archived email:
The bug I am encountering is this:
I have PPTP enabled on m0n0wall, and I would like to configure IP-based access
restriction to it. Unfortunately, no matter what blocking firewall rules I
apply to the WAN interface (blocking TCP 1723 for example), access to PPTP is
allowed from all IP addresses. It seems that there is a hidden “port 1723
allow” rule somewhere in the firewall rules.
Perhaps what is needed is a feature to disable the implicit 1723 allow rule?
Thanks for developing a great product. m0n0wall is the best!
