    Default Internal NAT Question

    I have a 2nd IP aliased to external interface with all traffic bound for this address forwarded to an internal server. I want all outgoing traffic from this particular server to be NAT'd to the aliased IP address of the external interface and not the default external address.

    Is this possible? Would it be a matter of creating a new NAT rule under the internal interface or would it take more?

    Regards,
    Matt

    Default Can be done but how...

    I posted the same question on Dec 01 http://forums.untangle.com/showthread.php?t=6277 and have not had any replies. From what I read it can be done, but the question is how.

    I setup a nat on the internal int using the 2nd IP for that int IP and have been testing various configs with Port Fwd and FW rules. But no luck yet....

    You need a nat policy on the adapter pointed at the server in question...

    config -> networking -> interfaces.

    Edit the appropriate interface...

    Then the policy is like this...

    0.0.0.0/0 auto

    Change this to ip.of.your.server/32 external.ip.you.want

    That did the trick.
    NAT Policy does the outbound and Port Forward rule did the the inbound.
    THANKS!
