Public IP addressed Machine

[Bashiraad]

I have a pc with one nic, which is configured with a public IP address.

what is the easiest and best way to add this pc to the domain?

Some solutions were, second nic and vpn

Thanks

You will need to provide us with more information before we can even begin to answer your question. We need to know more about the topology of your internal network for starters (are you behind a router, firewall, etc.?) How big is your network?

When you say "public IP" address, do you mean it has an internet IP address?

Public IP is an internnet IP address, lhuegele. If you want to add the pc to a domain, as in a private network with a domain controller server, then the correct (and safest) way to do it is to attach all nodes to a switch, and then the switch is uplinked to a router, and sometimes (like with dsl), the router has the switch built into it as a switch module, which is simply a layer two module built into the router for connectivity. The router will usually have a public IP address assigned by your ISP to the interface facing the internet, if it serves as an internet access device, and the interface that faces the private network would have a private IP address assigned, and can usually divy out private IP's in the same subnet to other nodes attached to the switch module.
If you have a pc right now with a public IP address, then you are just begging someone to break in and do whatever they want. A router that can change the private IP addresses on the network side to a public IP address incorporates a service called NAT, or Network Address Translation. One of the ideas behind this is because private IP addresses are not routable on the internet---public IP's are, which it is bad practice to have a public IP on a pc.

Hi burtsbees, but you haven't told me anything I don't already know, and Bashiraad doesn't give enough information for me to know exactly what he's asking...

Thanks anyway

My apologies---did not mean to offend anyone here.

Hey Burt, no offense taken! I agree with you 100%, especially about the PC having a public IP address asking for someone to break in....I wouldn't do anything if it wasn't behind a router and firewall.

Take care!
