VPN General Question
----------
Hello, I'm hoping to
resolve something in my
head before implementing
a VPN between two small
offices with 10 computers
each.
If I use two
Linksys BEFVP41 VPN
routers, one at each
office, and each is set
to serve up ip addresses
on the default range of
192.168.1.10x to each
lan, what happens when
the VPN connection is
established?
By
default, the 10 computers
in each office will have
ip addresses of
192.168.1.101, 102, 103
up thru 110. It would
seem there would be all
sorts of conflicts with
IP addresses, nbt names
etc. Can someone please
explain how this is
handled? Thanks.

nat
----------
that is what nat is
for.
p.s. why not
change the addressing
though. that would be
easier. | xidium

Is there no moderator?
----------
Sorry, I just thought
there'd be a moderator on
this site who would take
care of questions like
this that just sit here
waiting for relatively
simple
answers....
With
VPNs linking several
sites, a general rule of
thumb is that all sites
should have a different
subnet. That way there is
less chance of PCs on
various LANs having IP
address problems. The
routers will take care of
connecting the different
subnets for you.
NAT
has nothing to do with
it: in fact, a VPN
connects two ACTUAL
networks - there is no
need to translate private
address pools into a
public IP and back. The
encrypted tunnel between
sites takes care of
security.
Hope
this helps! |
