OK, this is a bit of a weird one. Our small office users (about 5 people) have for years accessed their desktop remotely using Remote Desktop with a little hack I put in to allow multiple users to access their own desktop. Basically, I use the fact that ports 3390, 3391, etc. are not being used otherwise, so I put in the router (simple Linksys) port forwarding so 3390 goes to, for instance, 192.168.1.12 and I hack the registry on this computer to set the RDP-Tcp to 3390. (also, I make the computer address of 192.168.1.12 static, not from DHCP). So this works great, and everyone seems to greatly prefer this over logmein. They are just fixed in their ways and I can't change them.
Now, we are relocating to another site where we are sharing offices with a bigger organization and they are providing the internet to us. So, they already have a router and server. They don't want us touching their router or server. Wondering if I could still use the router we have, shut off DHCP, make sure all our IPs are set up within the address range of their router/server and still have our router do the port forwarding to our computers as it always has. I can't figure out if this will work, but I can't see why not. Anyone know if it definitely will or won't?
