Sounds like you need the external router (172.28.13.* <-> internet) that
supports VPN. Once you are in via VPN, you should be able to see the
internal router (92.168.2.* <-> 172.28.13.*) and VNC via port number into
the 92.168.2.* PCs.
Am I understanding this correctly?
Would a headless Linux box do? Say, Smoothwall?

Subject: [SLUG] A question of routing
Folks.
I have the following scenario
a set of large machines which each has a internal network of computers, All
computers communicate over a internal network via a switch.
I now have a need to VNC into each one of those computers, I can do it as
follows. I replace the switch with a router which has a 8 port switch on the
LAN side. I set up each machine with VNC using different ports, i.e.
computer one uses sceen 0 (port 5900)
computer two uses screen 1 (port 5901)
computer 3 uses screen 2 (port 5902)
In the router I have set up on the machine, I have set up a routing table
based on the port number so a VNC request with a port number of 5900 is
routed to computer one, and so one. This works, I have tested it and have
had all of the internal computer screens on my desktop at the same time
(long live VNC). Now this is all fine and dandy but most installations will
have many of these machines so I need to put a second router between all of
the machines and the outside network, indeed this router will have a VPN so
the machine can be accessed remotely. I am not going to publish the
individual router addresses of each machine, so what I need is a router that
can take a URL and use it to route the connection to the correct machine
router.
Here is a example. I have two machines, machine one has a address of
92.168.2.11, machine two is 92.168.2.12. The router that is in front of
those two machines is 172.28.13.241. So I need a mechanism that will allow
me to establish a connection via the 172 addressed router. I am assuming
that most of the low end routers do not have enough smarts to do this. I
have done this with a linux machine where I had a alternate video source
along with those that are on the linux machine, (it is a zone minder
machine) in this case if you go to www.abc.com/zm you get the zoneminder
app, but if you do www.abc.com/192.168.3.123, you get a camera that does not
support ZM but I do need to look at it's video every once in a while. I need
to do the same sort of thing with this router which sets in front of all of
the machines. What are your ideas?
