    Lucidata Firewall

    Hi folks,

    We recently purchased a Lucidata firewall off eBay (I work for a community centre) to protect our small network but, my ignorance regarding the use of this appliance led to an issue with our Win2k Server not being able to resolve it's own IP address (see the other thread from me in wich I was supported enormously by the mighty Moby ).

    Anyhoo, at least we managed to sort the DNS issue which was causing loads of issues

    Now, though, we have to configure our firewall to allow the Win2k Server to act as a DNS server and, tbh, I ain't got a clue (sob)... and we could do with getting it online ASAP.

    I've had a go myself and initial support from Lucidata (even though the unit is second hand) was optimistic but that, sadly, has dried up...

    Any help with this appliance (it uses a piece of software called keycutter) would be very useful and appreciated.

    Thanks guys,

    Karl.

    What did you try doing so far? Have you hooked it up yet? I believe it should go between your modem and your router/switches. Your server will obviously be inside your router/switches, so there shouldn't be any special configurations necessary for your server to continue to operate as a DSN and/or DHCP server for internal clients.

    Of course, I'm no expert at all, and Moby or Paul will probably show my errors.

    Unless the "configuration" you're talking about is just "best practices" for which ports you should open, and which you should block, etc... in that case, I have no clue, since I don't have a special hardware firewall.

    Having followed the previous thread I'm going to stay away from this. What at first seems a case of opening relevant ports etc etc and setting up DNS to forward to/from ISP is a lot more complex given the nature of this beast! I'd love to help, but I fear I'd only make matters worse.

    Lol, thanks man, it's the thought that counts ;-)

    It's easy enough to get it going (you just write on the keycard what computers can access the internet) and that's it really. It caused loads of issues recently though as it interfered with our DNS server and if it wasn't for the might Moby helping me rule out EVERYTHING else I'd probably still be stuffed!!

    Thanks guys,

    Nimble.

    You need to allow the DNS server outbound on Port 53 UDP and TCP if its any help

    Now that's more like it Big-M comes to the rescue again (thank god). The keycutter software is a wee bit abstract though so I'll have a go at seeing if I can actually find the options to set the port permissions and post an update.

    Thanks folks.

    Think I've found the sttings - it allowed me to specify allowed services for the server so I specified DNS. It also has options to manipulate Hi & Lo ports - any ideas if these'd help?
