Map to drive on another network

Which ports do I need to forward to map to a drive on another PC behind another router?

Here's my network setup.
-2 routers (call them 'RouterA' and 'RouterB')
-RouterB is connected to RouterA so RouterB has external IP of 192.168.3.100
-the comp I am using is connected to RouterA as well (has IP of 192.168.3.101)
-the comp I would like to map a drive to is connected to RouterB (with IP 192.168.2.3).

Thanks

I'm not sure that this is possible at all.
I tried to do this some time ago but didn't succeed. I think the reason is that the IP addresses in class 192.x.x.x are non routable.
Can you see the drives on the computer on the B router from the computer on the A router? or the other way around.
If yes I surely would want to learn more details about your setup

<<< Try my next post first, UNLESS you really intend to have the machines isolated. If so, then THIS should work >>>

I believe you are right, that it WON'T work this way 'cause of the IP addresses. There needs to be a COMMON address. If you were to use a THIRD router & "tree" them so that the first one gives the other two a common "network", I think it will work. - you COULD use a hub in place of "router one" but the ISP would see two connections, so I THINK this is probably the cheapest & maybe the only(?) way to do it.

(ANYONE ELSE have something else in mind, in either case, this one or the one below??? - jump right in, please!)

as an example:

cable modem
|
|
|
router one----------- router three
|
|
|
router two

The cable modem would give the ISP's address - router one would provide 2 & 3 with say 10.0.0.1 - 2 & 3 would give the computers whatever... 192.168.0.1 & 192.168.2.1

Hope this makes sense! Wink

I got rereading what you have set up & what you are trying to do. I have basically the same thing going here that "I THINK" you are trying to do. I just hope you aren't trying to isolate the two machines to there own networks, or the following won't work.

I have my computer plugged into my main router & in that router is also a wireless router so that another computer in another part of the house has access without running wires. The wireless is on a different subnet than the main router but the main one is the DHCP server (this is OFF on the wireless - it will mess things up, otherwise) BUT (& this is the key) ALL the computers are on the SAME subnet address of 192.168.0.X

So again all has to be using a common address to work. How this is working, going through the wireless router like this, beats the **** out of me, but it is... - somehow the wireless computer is able to get an address from the main routers DHCP - I haven't looked at what I did here for about 1.5 years so I MAY have done more than mentioned to get it to work as it does.

As I recall, I wanted the wireless network on it's own subnet & I HAVE to set my computer to the wirelesses subnet to access that router so the ROUTER is at least on it's own.

I hope I haven't confused you - let me know what happens... & if I can offer any more help.
