AFAIK, all VPN solutions require different IP subnets on each end.
Sometimes the only way you can fix something is to change what you
have control over. I would suggest an even more obscure subnet in the
172.16.x.x range and pick a long weekend...

If the m0n0wall is using this LAN DNS for its DNS and DNS forwarding
is enabled, it should forward any DNS queries to the LAN DNS. This
assumes that the LAN DNS is using your ISPs supplied DNS as forwarder,
otherwise your LAN DNS will not be able to resolve anything. Think of
it this way: your PPTP client will ask the m0n0 for DNS resolution,
the m0n0 will ask your LAN DNS for resolution, your LAN DNS will ask
your ISP's DNS for resolution (if it does not already have the
answer). And they will tell two friends...

Do you have each client PC on your LAN printing directly to the 6
printers? I would share from one of your severs... Change the printers
IP and the only machine that needs to be told of the change is the one
acting as a print server.

Does the partridge or the pear tree require an IP?

Good luck and have fun.

p.s. If you are not having fun, you are not doing it right...

Subject: [m0n0wall] PPTP client and server on same subnet...

I recently set up a  monowall firewall at my office and am trying to
the PPTP vpn server working.  The problem I'm running into is that my 
office subnet is set to the very popular 192.168.1.x.  This ofcourse
the default setting that linksys, and may other, routers are set to.
when I log into the VPN from my home network (via my linksys router
it's 192.168.1.x subnet) it doesn't work, of course. Changing my home 
network to something like 192.168.0.x solved the problem for myself,
we have many people who travel and log in via networks that they have
control over.  So next you are going to tell me to change my office 
network to something obscure like 192.168.87.x right?  Well that is 
easier said than done because our office network consists of  at least

10 servers, 6 printers, 4 access points, 2 dhcp servers, 1 wireless 
bridge and a partridge in a pear tree.  Reconfiguring our network
be difficult, especially reconfiguring  each computer to recognize the

new static ip of the printers.  So my questions ars... Is there any 
other way  to get this vpn to work?  Will the new software with
solve this?  Do I have to reconfigure my subnet?

Also one other question... when I log into the vpn from home and do an

'ipconfig -all' it lists the ip address of  the firewall/pptp server
one of the DNS servers.  Where on the monowall can I edit the DNS 
settings and push some custom entries like 'fileserver -->'. 

Thanks for any help.
