Two IP's for Single WAN

Airtime
I have an interesting problem. Our ISP has only provided us with a single active ethernet port that we connected to the WAN of our Sophos UTM 220. I've been trying to install a PBX (from another company) that requires a fixed IP on it's own WAN connection.

I was hoping to be able to direct traffic for this second IP (different from the one assigned to the UTM) over the same WAN on the UTM so that I could have both be available on one ethernet line. Does anyone have any good ideas for how to do this, I haven't been able to figure it out.

    Hi, 

    1. I don't think you can use VOIP security if you have multiple remote clients.


    2. I think your DNAT is wrong.
    Leave the destination service blank, and if that doesn't help, please post a screenshot.

    Leaving the destination service blank seems to work. I'll try this and see if it works.

    I've things partially working. The problem is that the PBX seems to be statically configured with two interfaces. The internal is probably hardwired with 10.40.0.1, which is on the correct VLAN. The external is hardwired with the public IP. Since I can't configure this differently, I can't DNAT packets destined for the public IP address of the PBX to it's external interface. I'm not sure how to allow that interface to receive requests on its external IP.

    I'm kinda stuck here.
