    Default IP Aliases

    Hello,
    I have a wan ip 12.119.2.221 with gateway 12.119.2.220. I set it as an interface called interface test on untangle and I am able to get internet directly connecting to it.

    I then have a block of public ip addresses as follows
    LAN IP Information:
    IPV4 Block: 12.50.18.152/29
    LAN IP Gateway: 12.50.18.153
    First Network Assignable: 12.50.18.154
    Usable IP Range: 12.50.18.154 - 12.50.18.158
    Broadcast IP Address: 12.50.18.159
    Subnet Mask: 255.255.255.248
    (addresses changed for privacy)
    I tried adding the block above as ipv4 aliases but I am not able to get any traffic to connect. I am testing an unmanaged ATT router setup. I am testing on a laptop with a nat ip address. I am not sure if I have to set a default route or something because this is an unmanaged setup. I am confused. I have attached my setup in the image.

    Thanks,
    Nate

    I also set a static route to route 12.50.18.152/29 to interface "interface test" Before that I added 12.50.18.154 as an ipv4 alias in the interface.

    Post a screen capture of the WAN and LAN interface of the Untangle.

    Changing your IP addresses doesn't help you, it doesn't protect you, it does nothing for you, it only makes things harder for us to help you.

    You do not ever need static routes for traffic destined to IP addresses assigned anywhere on your Untangle server.
    NAT policies are best left until after you confirm the IP configuration works.

    Now, if I'm interpreting this correctly, you have an ISP that's routing you a network block. This usually means your External interface is configured with a single IP address in a /30 range, because the only two valid IP addresses in that block go on your router, and the ISP's router. Then you have a usable IP block the ISP is pushing to you. Typically, all you have to do is assign these IP addresses as aliases to the External interface and they'll just work. Note, aliases are singular entries for a single IP address, you cannot input ranges here. So you'll need one alias per active address in the range.

    There are other options, especially if you want Untangle to bridge a public address somewhere, but let's start with easy. But it's hard to determine what exactly you're trying to accomplish from here.

    Thanks for the responses. I am paranoid about putting my ips out there:
    Here are the images showing the port forward rules and interfaces:

    - Add condition protocol = TCP and UDP to port forward.
    - Remove any static routes added.
    - Does 172.24.12.189 have the gateway of 172.24.0.12?

    I just noticed, the IP of 12.50.18.154 is outside of your /30 range of the gateway. How is that IP assigned to you from the ISP?

    I removed the static route and I added the protocol for the port forwarding. as shown below. I am wondering if the netmask for the ipv4 alias is right?

    That is the thing I think I am missing. The ISP keeps saying I need to set a default route that is why I set a static route.
