Star2Star VOIP - UTM Setup

Phreeze

My question / dilemma may require several steps.  I apologize in advance.

 

Star2Star is a VOIP provider in which it is somewhat proprietary / closed / locked down.  I inherited it and must live with it for a while.  They require their little "black box" have a Public IP address and sit at the edge of the network.  I'd rather not have a switch in front of my UTM/s in order to "Split" the internet connection.  They of course want their box in front with everything running through their box.. no thanks ...

So how do I make this work?

1. Physically - Can I just plug the box into any port on my SG210 and configure an interface and give it one of our Public Static IP's .

2. How do I let the connection to the Starbox be Open so it can communicate with Star2Star's systems ? 

3. Internally all the phones must be on VLAN 41 (Tagged) to work.  The Starbox hands out the DHCP address to the phones.  How do I let this happen/ work ?

 

Let's start there.

    Hi  

    First, you can simply plug the box to SG 210 on any of the Port but you will have to provide that Port an IP address in the range of VLAN41 (If it needs to also provide DHCP address to phone in the network). If you have a public Static IP and a different Gateway (than your WAN interface of UTM9) you may simply configure it that way.

    Second, you can use a DNAT rule provided you know how many ports are required to be forwarded to the box (also restrict it for the Star2Star's IPs).

    Third, you can configure a DHCP relay on UTM and ask the box to provide DHCP addressed.

    PS: I've suggested based on what I could interpret from your post. If you can provide more details, we can discuss and improve the plan to do that.
