MONOWALL WAN

2006-09-01 Thread Laurie Zimmerman
Hi,
 
I have a client who would like to share a DSL connection with a neighboring
office.  I would like to put my clients network (they only need to share
Internet) on a separate IP network behind a monowall.  My question is, will
monowall allow a private address (the LAN IP of router) to be its WAN
address?
 
Thanks
 
Laurie

my firewall is pfSense, which is based on monowall.

on pfSense, in order to use a private address on the wan interface, you have 
to uncheck a box that says block private networks (it even says 'for the 
purposes of putting the wan interface on a private lan).

i would assume due the lineage of pfSense, that monowall likely has a similar 
feature.

hth,

Hi Laurie,

I'm not sure about monowall, but I know for sure that an OpenBSD or
FreeBSD machine running OpenBSD's packet filter will do the trick very
nicely. Check out pf(4) and pf.conf(5) or the FreeBSD Handbook on the
subject. You can also grab a copy of Jacek Artymiak's book Building
Firewalls with OpenBSD and PF, 2nd edition which covers pf(4) very
well.

Some URL on the subject:
