Hey guys just have a question about a network setup. A friend asked if I could take a look at his small office network to see where any improvement can be made.
i noticed that he had a dedicated box running untangled to server as a UTM system. Basically the setup is… Internet -> untangled box -> cisco rvs 4000 router -> switch ->lan.
My question is… is the untangled system redundant? They do very little internet usage, basic browsing. They do not run any web or remote access services, so I think the exposure risk on the internet is minimal.
Would the NAT & firewall from the cisco router be enough to keep the network secure?

Thank a lot guy appreciate the help

If he already has the Untangle Box in place, with no problems, then I'd say that it would be best to keep it there. It's better to have a little more protection if it's not going to cost anything more or require any more work to have. It's been a while since I looked into the Untangle Box honestly, as I've gone to Sonicwall systems for the purpose of doing all the firewall and routing through a single well-supported and cost effective system. But if they have this in place, there's no new expense involved, then I'd say keep it as is unless you are having issues with it. You may need to check and see if there might be any throughput issues is all, but this is going to depend on a lot of factors including your internet connection...

I'd agree that since its already in place and working properly just leave it, however we are limited on space and resources. we are needing to add an addition server for file and printer serving. If the untangle box is only adding a bit extra security, i would prefer to convert it to a file server instead of having to purchase a new box which would be taking up even more space.

2nd question, would running untangled as a virtual front end in hyper-v be a viable option?

thanks again for the help guys

If you are needing to repurpose hardware, and the Untangled Box fits your needs, then I don't see why you couldn't set up the system with a Hyper-V virtual machine on existing hardware. It doesn't need a whole lot of system resources to run, but I would highly recommend configuring your virtual switch interfaces for that VM to directly pass through to physical NIC connections on the server for ease of management and performance.
