Wireless and manually assigned IP#s

[maceyhw]

I have a laptop which connects to two wireless networks, one at home, and one at our small business. I would like to be able to access it remotely (XP pro remote desktop connection) at either location. Since it appears and disappears from each network, the laptop's IP changes pretty frequently. In order to set up the port forwarding, I'd like it to have a stable IP on each network (doesn't have to be the same, but that seems easier).

Before I mess with our network, I'm trying to do a little research

Does anyone know:

1.Can DHCP and a manually assigned IP address coexist, or will I need to turn off DHCP on both routers and assign all machines in both locations IP addresses "by hand"?


2. If I manually assign the laptop an IP address, will it retain it on both wireless networks?


Of course, to further complicate things, one of the networks is WEP encrypted, but I don't think that will matter, it's configured to connect to both networks correctly right now

(yes I know WEP's not very secure, but for some firmware reason, MAC filtering doesn't work on that router and WEP was better than nothing)

Anyway, this is sort of a pie-in-the-sky project, but if anyone has any insight, I would greatly appreciate it.

Thanks

most soho router have an option to always set a ip to a certain machine while also using dhcp. Look in the router config under dhcp settings.

if you're not working with soho routers, then you should be able to change the pool of dhcp addresses (scope?). leave out the first few addresses of the network and assign them manually.

This is what I do. I have my lappy that I use my wireless with that I also run a P2P app on. I've set up my FW to allow the ports so in my router (Netgear WGR614v4) I have a place in the DHCP config that let's me assign the same IP using the MAC address of the wireless card. That way that card always gets the same IP and I don't have to reconfigure the FW every time. HTH
