Subject: RE: [LARTC] Help with gre
tunneling
The short answer would be yes, but there are lots and lots of
details.
Now that your GRE tunnel is up and running, switch your thinking
to
look at it from Windows' point of view. From Windows' point of
view,
the GRE tunnel is really a router. So you have LAN A connected
to
a
router, across a WAN, to LAN B. Your Windows PCs have
no
clue that there is a GRE tunnel in-between. All they know is,
their
default gateway is the internal IP address of the firewall/router
you
set up. Well, maybe not their default gateway, but at least
they
have a route to the LAN on the other side of the
tunnel.
So
what do we need with Windows so that PCs in LAN A can
browse (Network Neighborhood) shares offered by computers
in
LAN B? Assuming Windows 9x, we need a way
for NetBIOS name
resolution that doesn't depend on broadcasts, so that means
you'll
need a WINS server in both LAN A and LAN B. You'll
want to set
up
the WINS servers as push/pull replication partners so they
both
have up to date copies of which systems are where. And
you'll need
to
set up your PCs as NBT node type 8 (I think). This is the
hybrid,
where PCs first try to resolve names by asking a WINs server and
then
try a broadcast if that doesn't work.
You could also use local lmhosts files for NetBIOS name
resolution,
but let's not even go there.
If
you have a Win2000 domain and all Win2000 clients, then the
rules
are different. In this case, you'll need DNS servers instead of
WINS
servers.
Conceptually, the point is, you need some way to do name
resolution
on
both ends of your tunnel to make this work.
You will want to set up some kind of Win NT or Win 2000 domain
structure that makes sense, or you will want some kind of
workgroup structure that makes sense. So let's say the PCs
in
LAN A are all members of a workgroup named LANAWG. If
you
make a PC in LAN B a member of the LANAWG workgroup,
and
you have name resolution that works, then that LAN B PC
should
be
able to browse its Network Neighborhood and see the
shares
offered by PCs in the LANAWG workgroup, no matter which
side
of
the tunnel they are on.
This all assumes that the Windows PCs do their jobs
properly.
