I want to attached though a wired system the 123 IP address to the network so that it can also access the internet attached to the network.

easiest way is to change the 192 network to a 123 network. No cost associated.

Without knowing exactly what the Static IP address you refer to actually is any solution is pure conjecture.

Is this IP address a public IP address or a private IP address like

Whatever "an item" is, why don't you simply add a secondary ip address of 192.168.1.x to that "item" and configure the default gateway on that item to the router?

The original poster should always write the last response !!!
Let us know, if the problem is solved !!!

I have to admit mark30504, your question around a static ip address on a lan tells me the knowledge on how to change that ip address isn't known at this time.

It's a different story if that static ip is a public ip.

The next step, if no ip change [if using dhcp server is very easy], is put in a router.

Putting in a second nic only works if you remove the gateway entry on one of the interfaces.

Hello All

Some additional information

Customer Network IP can not be changed
Yes it can but custom is not going to do this.

The "Item" a web enabled industrial SCADA circuit board
(IP to be considered unchangeable)
Yes, its changeable if you can plug into it RS485 and have the correct software.
But its 2000 miles away and software is propriatary and not sendable to customer
and don't want to incure the cost of sending ethernet to 485 hardware and talking to it remotely.

As to pubic / priviate

Its a standard office, a number of computer on a networks and a router device to give them internet access.

My thoughts were a bridge or router.

Just wanted to get a opponion from someone who has connect two LAN connections that might be similar to my situation.
