    Default Additional public IP

    Right now I have 3 nics in my untangle box.

    1st: External WAN
    2nd: Private LAN
    3rd: NIC for new external IP address.


    I can not get things to flow through the new IP address on the 3rd NIC. I have done the port forwarding, and the NATTING. Can someone please just point me in the right direction. Do I even need the 3rd NIC to use my new public IP?

    Typically the IP comes over the same WAN port. You just set up NAT and firewall to point it where you want it to go. I'm still new to Untangle so I'm not sure how they handle it. On my other firewalls I create a new object with the new WAN IP and then NAT it to the destination.

    can you show us a network diagram? If the new IP address is indeed coming from the same ISP, you'll want to add an alias, something like this:https://wiki.untangle.com/index.php/1:1_NAT

    Merry Christmas!

    I have followed that very same link Ninja

    So now I plan to use my 1 WAN port for multiple public IP addresses.

    1. I created the IP alias.
    2. I created the 1:1 NAT rule
    3. I created the port forward and firewall rule

    I can not access the the network from outside. Any suggestions?

    If you created an alias, you didn't use a 3rd NIC.

    You cannot multi-wan within a single ip network. We'll need actual IP addresses, and which interface they are on to assist further.

    If you aren't trying to multi-wan, disable that third interface you won't be using it.

    You add an appropriate IP alias on External, that will allow Untangle to start using the new address.

    Finally, you configure Untangle to use the IP address in question.

    Ingress traffic, is handed via port forwards.
    Egress traffic, is handled via NAT Policy.

    If you have a more specific question, we can help with more specific answers. But from what I'm reading here, you're a bit lost on what you're attempting, so I'm a bit lost in providing direction.

    Sorry if I'm not being clear. I am now trying to use just one WAN interface. I have created the alias, I have created the NAT policy (that may not be 100% accurate as I'm not an networking expert, however, I did follow the instructions I found online.

    I already have port 80 and 443 being forwarded to another server. I want port 80 and 443 for the new IP address to be forwarded to another server. Doesn't seem to be working.

    You need to use advanced forwarding rules, and manually specify destination address : WAN IP address.

    Then the rules will trigger for one vs the other. You do not need a NAT policy if you're just trying to get two web servers exposed, the port forward is enough.

    For further assistance I recommend a screenshot of your NAT rules, and your port forwards.

    where are you testing from?
    what does https://www.whatismyip.com/ tell you?

    can you provide screenshots of the rules?

    I can not get to whatismyip.com as this is a headless setup.

    I am working on getting the rules setup.

    Use of whatismyip.com isn't assumed to be from Untangle's console, it's from the machine you're building the NAT policy for.

    This is why he asked WHERE. Because you're testing from the wrong place it sounds like.
