Just had a successful deployment of a Nethserver to replace an aging Untangle. I used an old IBM x346 server slapped with a 3Com 3c980c for additional ports (Donald Becker, thank you).
I have a multi-wan setup with 7-8 different groups sharing the Internet. I bonded the remaining ethernet for the Green interface.
Since Nethserver does not have a way to throttle bandwidth per group, I accomplished that by putting them all behind a Cisco switch and do it from there.
Only problem now is how to get some Nethserver swag.
What I like about Untangle is that each service is independent from each other which are basically two things: rules and logs.
Untangle has a rich pre-defined rules that you can just enable/disable at will.
Untangle can be easier to use for people who are new to firewall+utm.
A website got blocked? Check the Web filter rules and logs. Untangleās Web filter also allows you to block a site and add a comment/reason that the user will see on the page.
I really have to give Ease of Use points to Untangle. I can monitor what went thru and what was blocked by each module without having to grep/awk logs.
