    External IPs...How Many?

    We currently have two external IP addresses, one for our VLE, one for our email server.

    I'm wanting a thrid to run WebDAV.

    The ISP don't sound too sure about giving me another, am I being unreasonable?

    It depends . Are you expecting it for free? Chances are they will charge you for the third one (usually a nominal amount though).

    I was expecting it to be free yes. Though to be honest if it costs anything it won't be much of a concern as it's the Assistant head that wants it done so money will definately available!

    As public ip's cost your provider then I'm sure they'll charge you for it unless you talk to them really nicely.

    Is this the only way you can acheive what you want to do?

    Re: External IPs...How Many?

    I don't know. I shall explain.

    ServerA - email server. Ports: 25, 110. (has an Internet DNS entry of webmail)
    ServerB - VLE. Ports 80, 443, 3389. (has an Internet DNS entry of talmos)
    ServerC - WebDAV, Ports 443 (will need an Internet DNS entry of public)

    We use a PIX.

    Currently we have an two Internet IP addresses that go to two external addresses on the PIX, allowing the above ports. These external addresses are then NAT'd to two Internal IPs, one for each server.

    We now want to allow access to our Public Area, using WebDAV.

    I figured the easiest way was to just have another Internet IP going to another external PIX address then forwarding that to the appropriate place.

    Re: External IPs...How Many?

    Why not have the two Internet IPs forwarded to ServerB and C, and then DNS entry for webmail NAT'd to an internal one?

    webmail ext_1:25 => ServerA:25
    webmail ext_1:110 => ServerA:110

    talmos ext_1:80 => ServerB:80
    talmos ext_1:443 => ServerB:443
    talmos ext_1:3389 => ServerB:3389

    public ext_2:443 => ServerC:443

    Would that work for your setup?

    Re: External IPs...How Many?

    I'm not sure webman, I guess it would on paper.

    Trouble is I don't have any PIX experience so getting the changes made requires getting paid help in.

    Would the DNS changes be internal or external? It takes a while to get them done if it's external.

    To be honest I just wanted to implement this without fiddling with anything that's already working. If it means we have to pay a bit I think it will be worth it!
    Though to be honest, the amount we pay this company I don't see how they'd have the face to charge us!
