Remote Desktop

[beermaker]

I'm fairly new to networking and need a little help. I'm trying to replace an old netgear switch attached to a 3 port linksys router in my new place of work and don't want to screw up the RD port scheme.

Users have been connecting to their LAN from home via the ip of the router and using :100(X) (X=some number) after the ip. I figured out the :100(X) is the port on which the specific system is located but can't get net access to the switch thats "channeling" the separate ports. I hope this makes sense so far.

My goal is to to replace both the switch and router with a new larger router and get rid of the current setup. How can I tell what port connects to what system for remote desktop?

thanks for looking,

The router should designate what ports get forwarded to what internal addresses. You should see something like the following in the Linksys config: http://homepage.mac.com/car1so...nksys_port_fwd_afp.jpg

The switch makes no decisions on what goes to what. All you need to do is copy the current config from the Linksys router to the new router and you'll be fine (i.e. port forward all the ports currently set in the Linksys to the same IPs).

One more thing to note - check how those IPs are setup. Check in the Linksys to see if they are setup with static DHCP entries or check if the client's have static IPs set on the PC themselves. If it's the former, you'll need to move those settings over to the new router as well.

Replacing the switch will have no effect...if the router stays the same, you are all good.

If you are switching from a combo Router switch to a Router with more ports.

It is Not fare to do so, since You Wasting you are Boss/Friend/Client Money.

As mentioned above the switch as nothing to do with the ports or the IPs.

99% of the people that use Entry level Routers use a switch if they need more ports.

Their is No technical advantage in more ports on the Router per-se, and the 8 or more Ports Cable/DSL Routers are expensive and Not the best on market.

That's it exactly. I was looking in the wrong area of the router. Once I went to the port forwarding I found all the info I was looking for.

Thank you - much appreciated.

A side question - Since a normal switch operates on layer 2 (using MAC addressing) it makes no decisions as to where these packets are forwarded right? So the router operating on layer 3 using the IP address makes the decisions. Or am I off base entirely

It depends. The first thing a PC does to communicate with another PC is to perform an ARP to get the PC B's MAC address. If it's not in the same subnet, it'll forward the packet to it's default gateway (the router). If it is on the same subnet, the switch will get the packet, look at it's CAM table and forward that packet to the port the other PC is plugged into, not requiring any communication with the router itself.
