I don't know how to describe my question without sounding like an idiot but here goes: My office has a DG/UX unix system that we are able to telnet to via TCP/IP through an NT network using an emulation software. We have internet access set up on the NT network via a cable modem and I want to be able to set up our Unix system so that it goes through our firewall first and then out to the internet (i.e., I basically want to be able to ping to internet addresses (microsoft.com, etc.)) My knowledge of UNIX and TCP/IP is very limited and was wondering if there is a way to do this going through Unix's sysadm. Any assistance would be greatly appreciated. Thank you very much.

By the sound of it, you'll need to go through the Unix system's admin.
I couldn't decipher if you meant that the Unix system you telnet to was inside or outside of the firewall.
If it's on the outside of the firewall, you'll need the unix sysadminto setup the tcp/ip addressing to be on your LAN.
If it's on the inside of the firewall anyway and you want to go through it, instead of the NT network to get through the firewall and into the internet, you would still need assistance from the unixsysadm, and any other network admin to move some of the programs around for telnet serving, and changes to the firewall to have another machine let you through.
I hope this makes sense.... Good luck!!!

If you are not the system administrator you will need the system administrator to do this, as it requires root access.

The route command is the tool used to do this. Type
man route
for details on your system.

If your network onlyhas one segment, set the default gateway of the unix system to point to the router to the internet (or the firewall if that is a different box).

A typical command format would be:
route add 0

If your network uses more than one segment, your default gateway is almost certainly already pointed at a router, and you do not want to change this or you will lose access to part of your network. If the router is not the router going to the internet, you need to use the administrative commands on that router to establish a default gateway pointing at the internet router (or the firewall if that is a different box).

Good luck.

Hi,
Use the route command, it should look something like this:
route add default destination-addr gateway-addr

Do a man route to get more info for the route commande under DG-UX

Good luck
