Other than the built in functions? This is kinda the purpose of Webmin. I guess the downside is it isn’t as ‘braindead’ an interface as what you would expect in a GUI. More of a ‘helps you manage’ what’s already there.
Howdy,
OPNsense is a fork from developers of PFsense but has more features for free.
Both appliances are a little intense to get setup and configured but offer amazing protection and adaptability for inbound or outbound networking.
I have started playing with OPNsense, as with anything new there are frustrations.
It appears that product development has far outstripped the documentation development and their forum isn’t sending out Activation emails (tried 2 different addresses including gmail) so I can’t ask for answers.
It certainly shows promise, though trial and error learning will take time that I don’t have.
