Hello,
I have a question, and maybe you'll find it strange, but I have worked with several firewalls before.
When I create or change any rule in OPNsense, I click the Apply button. However, the Apply button always remains visible, which can be really confusing. Sometimes, people think they haven't clicked Apply. It is not so in Pfsense.
How to fix it, is there any settings for it?
It would depend on the page, but in general for new style MVC pages we keep the apply button visible. It may also restart the service without making modifications or unbreak an otherwise broken service.
Cheers,
Franco
