private to public IP - terminal

By amf72 ·
Our LAN is connected to the Internet trough a Nortel Networks Contivity 100 wich acts as proxy, firewall, etc. Our public IP address is dynamic, so I've been told I need something like dns2go.
What I don't know is how to access a particular computer in the LAN since each has a private IP address. Any help will be greatly appreciated. Thanks in advance.

Accessing computers on a LAN is really accessing the shared resources[files and printers]. The computer you wish to retreive files contained in a folder has to "share" that folder. Once that folder is shared, the folder will appear in My Network places [or you may browse the network via Entire Network Places to locate a particular shared folder [or computer].

note: you don't need to know the IP address of a particular computer because that is irrevelent to a user that is trying to access shared resources.

if your using terminal services to log on to the domain, the admin probably has setup what you can and can not access as far as shared resources and what you can and can not "see" on the LAN. If a particular resource isn't available to you that you require, the network admin will have to provide you with permissions to access that resource.

I need to access this computer from the outside, and have total control over it, not just access shared resources.-

You are on the right track by realizing that you need to use dynamic dns. The next step is to determin how to securely access your network. Luckily the contivity series is also a vpn concentrator. You can configure your firewall at work to support Ipsec based virtual private networks. This will allow you to connect into the office lan without comprimising your security.

To access resoureces on your LAN directly (without using TS or any other termianl means). You will have to use either NAT or PAT. NAT means that you tell the NAT Server that all connection from the Internet (doesn't matter the port number) will go to one private IP address on your lan. PAT means that you tell your PAT (usualy the NAT server) server that if the connection is to port number 21 (ftp) it should connecto to IP address x.x.x.x if the port number is 25 (SMTP) it should go to IP address y.y.y.y
