    Default Bypass NAT for public address

    I've been hunting for the answer and can't seem to find anything. I had a ordinary router, doing NAT. I had a block of public address that I simply routed on the router and public addresses simply ignored NAT.

    I have not been able to do this with untangle. Wiki seemed to say that anything that is not NATed would be routed, so I unchecked NAT on both WAN and LAN interfaces, then made a NAT rule for my private address.

    If I use NAT rule instead of checking NAT box in interface, public addresses can't get out to internet but private addresses can.

    If I check NAT box in interface, public and private can get out to internet, but public addresses are still NATed...like whatsmyip.com shows the address of WAN interface instead of the public address assigned to a machine.



    any help would be really appreciated

    You're on the right track, but how did you define that public range?

    Your ISP should have a master address they've given you, and that's what's on External right? If so, you have to use one of the addresses in the range you've assigned to Untangle on a "lan" interface. Then the rest can be used on the equipment, with the address on Untangle defined as their gateway.

    I'll need screenshots of your interface configurations to do much else.

    Here is diagram. I don't have any NAT rules currently because that broke things and I'm not sure what rules should be there. I only have NAT checked for the interface. The way I have it now with NAT checked on interface 69.x.x.66 has net, by whatsmyip.com says IP is 58.x.x.10

    That's why DMorris asked for the map!
