RDP, Router & Dynamic IP

I finally figured out why I could no longer connect via Remote Desktop to my
PC from work or anywhere via the internet. I have the RDP port open on my
Linksys Wireless router for IP xxx.xxx.xx.100. When I restarted my router,
it reassigned the first IP (xxx.xxx.xx.100) to the Laptop (accessing
wirelessly), the second IP to the second router & the third IP
(xxx.xxx.xx.102) to the PC (connected directly to the router). Is there any
way I can assign a static IP to the PC?

One thing I'm thinking is if I have the laptop with me somewhere & the
router restarts for some reason, the IP's will be reassigned again.

I think you can force the IP and manually set the ones you need on each
computer in the TC/IP settings. just give it an IP in the routers range,
take off dynamic assignment.
 
The information in the link from 'Sooner Al' Note will show you how to
access the TCP settings, but it also contains a striking error in saying:
"When you set your computer to a static ip address, that ip address is not
handed out by the router. So the very same ip address may be handed to
another computer later, and that will prevent them from connecting to the
internet. So when you start assigning static ip addresses, you need to
assign a static ip address for every computer on your network."

The better, and far more common practice when a static IP address is needed,
is to assign it in the proper subnet but outside the DHCP range of the
router. Many routers, for example, start assigning IP addresses with
xxx.xxx.xxx.100. Standard practice is to assign a stoic IP of
xxx.xxx.xxx.65 (for example). We rarely, if ever, disable DHCP for an
entire network because one (or a few) needs a static address.

Also, note that since this is a laptop, if you use it elsewhere, Windows XP
Alternate configuration will allow it to receive an address automatically,
but there will be a noticable delay while it attempts to connect.

A restart of the router will not affect the static assignment you enter on
your laptop.
 
To add some routers allow you to assign the same DHCP address to a client
based on the clients MAC Address, a pseudo static IP address so to speak. I
do that with my laptop so it gets the same IP all the time on my home LAN
but gets a DHCP assigned IP at all other sites.

I only use static IP addresses for my desktop PCs, ie. PCs that in theory
never move from one network to another...:-)

The comment about setting static IP addresses outside the DHCP server
assigned is a good one...

Thanks GTS (& Sooner Al)... that's a lot of very useful information & tips
there. I'll have to give it a try when I get home. If all goes well, I'll
probably not post on this thread (or at very least a EUREKA post :-) saying
it worked).. If I run into trouble, I'll yell for help!!

I'm more interested in keeping a static assignment to the PC. I use the
laptop mobily or elsewhere in the house to RDP to the PC (either thru
internet or thru router... a VERY KEWL ability, btw). But, for certain
programs on the laptop, Sooner Al's helpful info :

based on the clients MAC Address, a pseudo static IP address so to speak. I
do that with my laptop so it gets the same IP all the time on my home LAN

& the link to step by step:
http://www.portforward.com/networking/static-xp.htm is going to come in handy.

His info & your info are going to solve my problem, I'm sure.

Thanks a lot!

Okay... finally got back to this. Set a static IP outside of the DHCP range
to the desktop (PC)... Then set the Port Forwarding for RDP to that IP. Now,
works great.. so far.

Question.. that sounded like a good idea about the MAC pseudo-Static IP.
How would I do that? Or, maybe better question, how would/can I do that on a
Linksys Router. I'm using the Linksys WRTP54G, a Vonage VOIP
enabled/modified Linksys router. Any info would be appreciated.

You could only do that if your router firmware supports that. Check the
router users manual or the Linksys support pages for help. Its possible a
firmware upgrade may give you that functionality...
