WEP and WPA on the same network - problem getting an ultrasound machine to work

    Hi, I've spent a really really really long time on this...

    I own a vet clinic and we have a network, mostly wired but also a WPA wireless network.

    We recently bought an ultrasound machine. It only supports WEP!

    So I want to use a Linksys WRT54G to make a WEP network and connect it (using the 'Internet' port on the back of the Linksys) to rest of the network. I need the ultrasound software running on the server to be able to 'see' the ultrasound unit.

    Here's the setup: - main router (connects to our DSL service) - server with the ultrasound software - 'Internet' interface of WRT54G. connects to our switch. - Ultrasound machine, connected by WEP to the WRT54G

    I thought by telling the ultrasound software to look for the ultrasound machine at it would work, providing the port-forwarding was set up. But it doesn't. I even tried making a DMZ! But it still doesn't work.

    I've spent several hours on this, without success. The ultrasound unit itself is fine, because if I make my laptop part of the WEP network and install the software on it then it sees the ultrasound unit.

    The idea is that the ultrasound user can save ultrasound images to our main server, and since no one else will be using the WEP, i can lock it down.

    I'd really appreciate some help!

    Not sure why it doesn't work, but guess its the nat translation function in the WRT54G. I recommend using the WRT54G as an access point only put everything in the "0" network and use the LAN port not the WAN port to connect to your wired network. You should turn off dhcp on the and use local static IP addresses I guess.

    thanks for the reply. how do I configure the linksys to be an access point only...? I don't recall seeing that option in the web admin.

    we have a fancy Dell switch, maybe i could use it to increase the security of the setup?

    ...or maybe i could just buy another wireless router, maybe that would work...?
