 MR> my VPN server and see the hood. I can ping some of computers. my
 MR> 192.168.1.120 ip only returns 50% packets. At home my subnet
 MR> 10.10.10.23 relies on my gentoo caching dns server. but that server is
 MR> 192.168.1. I'm not sure what to do.. my VPN server is hooked to my
 MR> 10.10.10 network but my routers tied to the network 192. the 10.10
 MR> network is uplinked to the router... I have the 10.10. network because
 MR> my local network is a gig lan.  they don't make gig routers yet.  How
 MR> can I force my XP laptop to use the VPN connection for all internet
 MR> traffic?  I use sprint network to get to my VPN.  Ummmm... I wonder is
 MR> there server software.. to check for mail and newsgroups and maybe call
 MR> home to my server and get mail from that instead of mediacom?  I'm sure
 MR> you have dealt with thi b4.   This is why I think I need to subnets.

Geez...  Dude... your probably confusing what VPN is.  Its a "Virtual
Private Network".  Means your opening a door up to your internal network
so you can gain access to it from outside.  You don't run VPN on something
that's already connected internal.  Now, the rest of the configuration has
to take place...  VPN needs to know what network IP range your connecting
to, hence your problem above connecting to your multiple internal
networks.  You really need to choose one and dump the rest of that crap,
your just going to cause yourself nightmares.  See, us network guru's have
a saying, which I'm sure your've heard of:  KISS  Keep It Simple
Stupid.  If I run into a nightmare network setup, the first thing I'm
going to do it try to streamline it, bring it down to acceptable ranges.  

Now, you can run 2 internal networks, and setup your router to handle
multiple networks, but, your going to need to spend some money on that
router.  Something like a Cisco 1600 or better, which can handle multiple
networks.  Then it does the translation between the 192.168 and 10.10
ranges.  Thats what its for... Little Linksys's and Dlink's just don't
have the capabilites that you are attempting to put into operation.  They
are one network, one network range devices.  Now, you could also use the
Linux box to be the bridge, but you need to take some of that other stuff
out of the way to utilize it correctly.  Putting 2 nic's in the Linux
system, and configuring them to cross over, would make it a router. 
For example, make the one nic on the internet side, using the 192.168
range.  Then put the second nic on the 10.10 range.  You can setup static
routes, local routes, etc...  That way the 2 networks can talk to each
other.  You have one "Gateway", which is your internet connection, and
both sides can talk to each other...  All this other "Fluff" your doing is
just that... fluff and eventually will cause you more problems than its
worth.

Just food for thought.
