They call it "SSL VPN" AFAIK.
Hmmm just noted that Sophos seems to miss OpenVPN - not shure I like that....
...so anyone who could correct me, and tell me I need not to worry?
I ran an old pc with Sophos UTM 9.x on it for over a year as my home FW.
Awesome product with nearly all features enabled. Some of the more business oriented such as managing Sophos anti-virus clients are disabled on the free ver & its important to know the free home version is limited to 50 active clients. That means 50 separate MAC addressed devices using the WAN.
I never ran into that limit but keep in mind, roku's, smart TV's, any internet connected device counts.
That's an active limit for the free UTM. Not the first 50 MACs it learns. Just 50 active clients simultaneously.
The ONLY reason I turned my router back on as the primary device is because Sophos UTM does not support OpenVPN right through the gui. There is some command line or other work around but in the end after 1 year I just wanted a simple vpn client to connected to Nord which Merlins fork does excellently.
Last two items I want to mention about Sophos UTM.
Its IPS is excellent. It actually alerted me twice in that year to an internal pc that was attempting to reach out and perform suspicious activity on the web. As in contact a command and control server (think botnet). That was very impressive to have it alert & stop that traffic. I was then able to clean the infected device after the fact. No home router has that ability I am aware of.
The learning curve of a true FW like Sophos is not nearly as simple as say a home router or pfSense.
Good luck with whatever you choose.
