    I have a WRT-54GSUK and am looking to connect my forth and final machine to it for a bit.

    What I want tho, is that machine to work without protection... IE, as if the router wasn't there... but at the same time, need it to share the internet connection.

    Is this possible? Was told DMZ does this, but just tried it, and I still couldn't run one particular software on it, so assume it didn't allow the computer to act as if directly connected to the modem.

    Thanks for any help... and if anyone wants to know why I'm doing this... it's for a uni project.:)

    what software were you trying to run on it? perhaps your ISP connection is blcking the ports your wanting to use? DMZ will open ALL ports for a IP address that is defined in the routers config, but without telling us what you are wanting to do or what your connection layout you have we cannot help.

    The software was small one (you wont have heard of it) - it works directly connected to the modem, but not through the router.

    I'm not too bothered about this app tho - I want a totally unsecure machine to be able to access the internet and be open for attack - But still leaving the other mahcines on the network secure.

    I am leaving it open for a couple of weeks and want to log all vulnerabilities and security issues on the pc after that period... hence, would be better as if not behind a firewall and router.

    DMZ is what you want then. it is support to open ALL ports to that NAT'd IP address. problem is the DMZ PC is behind a NAT router. so it will have an internal IP address. do you have access to more that 1 external IP address on your ISP?

    Nope... Just the one IP.
    Is there any way I can test its behaviour, and compare it to that of of a computer behind a router?

    DMZ should do it but if it doesn't, you can always try connecting your outward facing PC to the modem and also run DHCP on it and have a 2nd NIC connected to the router to dish out an ip to your router and/or computers.

    Try the Shields UP! service from GRC.com
    It can also scan individual ports on demand
