I am unable to get internet traffic through the UTM.

I have UTM Home v9.3551 virtualized on VMWare Workstation 10 on Essentials 2012 R2. I have a 4 port gigabit Intel nic configured as internal and external interfaces for the UTM. As my instance of the UTM is virtualized I have left my FVS318Gv2 Netgear VPN Firewall in place.

Current Configuration:

The external interface is connected to the vpn firewall with the internal interface connected to a 16 port web managed switch. The internal interface is on a different subnet than the internal interface.

Can the UTM work in this configuration?

Other configurations I have tried:

Internal interface plugged into the modem (partial bridge mode; static IP w/RIP on the ISP side) with the static IP information entered and the internal interface plugged into the switch.

In neither configuration have I successfully gotten internet traffic through the UTM.

  • I'm using Wokstation 10 and security is an issue because it is not regularly updated.

    I would love to use hyper-v but I'm running Essentials 2012 R2 and is only licensed for an instance of Essentials 2012 R2. I have considered upgrading to Standard but I will lose the media server functionality, so standalone hardware it is. I already have a case, psu, and ram, so the only items I need to purchase is a mobo and cpu.


    I kept bringing up double nating as a potential issue in Spiceworks for WAN connectivity and throughput but most people down played the potential or ignored it. I did plug into my modem with the external interface configured with my static IP but I still couldn't get any data through from a client. I was successful in doing a traceroute and ping through the external interface.

  • Regardless of licensing I'm giving hyper-v a go and so far so good. There were some irregularities when it came to updating the UTM software on Workstation 10 that have not happened with hyper-v.

  • Switching to hyper-v did the trick! I have the UTM running DHCP and clients have connectivity after releasing and renewing the NIC IP. I am still going through the Netgear for my external interface so I will conduct further testing to see what double nating will break and I have removed the connection between the router and switch so everything runs through my server.
