185429 2003-10-21 07:30:00 I'm trying to get a computer A (which has 2 NICs with different IP addresses) to be connected to a LAN but also be connected to a remote computer B.

I want only computer A to have access to computer B but also access the LAN and under no circumstances are the LAN computers to be able to access computer B.

It would be nice to switch computer A between the LAN and computer B without logging off, but it is not essential.

Does anyone have any ideas that may work?

Many thanks

185430 2003-10-21 07:33:00 I'm unsure what your problem is? This setup should work fine as it is.

What OS are you running? Is the "remote" machine off-site, or do you just mean that it's not part of the network?

computer A and B are both running Win2000pro, and you are correct in that computer B is on site but is not part of the LAN, only to be connected to computer A.

Should I put a different subnet mask on the NIC to computer B?

thanks

185432 2003-10-21 07:48:00 Make sure that you are using the TCP/IP protocol and that the LAN and computer B are on separate subnets. JohnD (509)
185433 2003-10-21 07:50:00 What is the problem? Can the other machines access computer B? Or can you not connect to it?

I don't think the subnet mask should be an issue.

LOL Maybe I'm wrong then :)

185435 2003-10-22 00:27:00 The mask has little to do with it. :D The masks used have to allow the machines to access their different subnets. Nothing will work if that isn't true.

The important part is to have the two groups on different IP networks.
If you are using the 192.168.xxx.yyy addresses, you will use a mask of 255.255.255.0 . Use, say, xxx=001 for the main group, and, say, xxx=002 for the pair.
That will mean that the hosts in the main group can't "see" the pair (except for the "multihomed" host).
