DNS HELP!

[ROSS HANSON]

I have a L2000 with an IP address of 192.168.*.*
This goes to a firewall where on the outside the IP address turns into 156.42.*.*
Our Clients all have Win98 on their desks and I am wanting to be able to telnet to the L2000 if I am working
on a clients system. I also want to telnet to my other
Unix boxes from the L2000 when I am on it.
The L2000 is our DNS server. When I try to do a nslookup or telnet from the L2000 to any other unix box (That's already behind the firewall) it sits and hangs.
Do I need to add a route to get from the clients system to the L2000 or must I do something else to get to any cpu from wherever I am.

Ross:

If you are trying to access the 192.168 server from outside your firewall, I am afraid you are out of luck because the 192.168 address are not routable on the internet. However, what you can do is to set up a listen address on the firewall which gets translated (or plugged-to) to 192.168 address of the L-class. (your firewall admin folk should know how to publish an address and plug it to the L-class)

within your firewall perimeter (inside your network) you can set up any routing provided that all the clients know how to get to the 192.168 network ( I am assuming that you have your wintel machines also having 192 address.)

in summary, this is what you should check:

1. Are you trying to connect to the 192.168 address from outside your fw? if so, get your fw admins to create a plug-to address and set up the appropriate static routes to the L-class

2. if youa re trying to connect from another 192.168 box inside your network, you should not have any problems, if you do, it is likely that your dns is not properly configured with reverse name entries.
