[vpn] Raptor mobile on Win 98 machine

The usual explanation is that you have a routing problem, although I
have a hard time explaining why that would be if an nt machine worked
and yours does not.

In general, assuming you are running the AltaVista Tunnel product, or
something newer, there is an endpoint at a tunnel server, behind the
firewall. You can "reach out" to other nodes on that internal network,
but each node with which you want to communicate must know how to return
packets: back to the tunnel server, which will then forward them back to
your remote machine.

So, for instance, if your remote machine running the Raptor Mobile
client has an IP address of 10.1.1.1, and the tunnel server has
10.2.2.2, you can ping 10.2.2.2 with no problem. However, (assuming a
class C here, all of 10.2.2.0), you will not be able to ping any other
node in 10.2.2.x. Suppose you want to communicate with 10.2.2.222. 

Your network administrator (you??) will need to put a route on that
machine -- 10.2.2.222, similar to the following:

route add 10.1.1.1 MASK 255.255.255.255 10.2.2.2

[note! this route is NOT permanent; once you have the correct route,
place the
 -p switch right after the add command]

there are additional arguments (this is for windows nt anyway), but you
should get the idea. You will need a specific route (like the above)
placed on each machine to which you want to establish a session from the
tunnel server. Perhaps the routes added for the nt machine(s) are in a
different IP subnet, which would explain why those worked, and yours
doesnt.

Faced with these kinds of problems, I keep a very simple batch file on a
server which, when run on a workstation, will apply all necessary
routes.

Clear?

HI,

I am trying to connect to our network using raptor mobile on a Windows
98
laptop.  I am able to successfully negotiate the firewall and get a
connection but I cannot access the network.  I can successfully ping the
IP
address but cannot ping the network.  

We have been able to successfully connect from a Windows NT workstation.

Has anyone had this problem and can anyone provide a solution?  Please
bear
in mind that I am a newbie to this and less technical explanations would
be
greatly appreciated.

Thanks in advance for the help.
