Replace ISP edge router with UTM?

Good day,

I've got a weird situation on my hands and not sure how to setup the routing.
We currently have two ISPs connected to our UTM and have recent ordered a third, a 100mbit fiber.
The new ISP has NOT provided a physical Cisco router, we were told to provide our own and the ISP provided us the interconnect IP block and the usable IP info.
Can we configure the UTM to take the place of an ISP edge router?
I don't know anything really about routing.. been trying all sorts of configurations with no luck.  Any ideas on how to configure the UTM to correctly pass this traffic?  Having the usable IPs 9.123.168.106 configured to an interface and using static routes for the rest?  This is a UTM 220 with lots of free interfaces.. 

Interconnect Network IP Address: 8.145.3.116
Subnet Mask: 255.255.255.252
Interconnect Default Gateway IP Address: 8.145.3.117 (ISP's pingable gateway)
Interconnect IP Address: 8.145.3.118 (To be assigned to our "cisco" router)

Network IP Addressing Information - Usable:
Usable Network IP: 9.123.168.104 255.255.255.248
Default Gateway IP: 9.123.168.105
Usable IPs: 9.123.168.106 - 9.123.168.110
Broadcast IP: 9.123.168.111

Thank you!! [:$]

  • Found the issue with the ISP. They didn't have our route in their customer router and added. Once complete, all we needed were to add secondary/aliases and set up proper SNAT/DNAT rules.
  • Steve, I have the same issue.

    can you tell me how you configured your Sophos I have an SG-125

    we are changing ISP's

    we have been assigned a /30 WAN Block

    and a /29 LAN block.

    I was told I needed a Router between my ISP and the SG-125.

    If I can do this in the SG-125, can the SG-125 handle the traffic.
