Your extensive config is probably your issue and not opnsense. You said you've been running it for a few years but seemingly 4 months ago, you couldn't figure out a basic rule to block internet for a single ip.
I second this. No offense to OP!
I never noticed any "slowing down issues" since any of the recent updates. Running OPNsense with a similiar setup to yours "vlans, plugins, policies, suricata, VPN, routes, gateways, HAProxy, etc". Again no issues on 8+ sites, including SiteToSite WireGuard VPNs and with large corporate networks. Some systems running perfectly stable and performant since version 20.x (installed) and now running the latest update.
Therefore I highly think your issues are user error / misconfiguration. Yet, I don't mean to judge but it seems to me that you switching to pfSense will just bring your OPNsense issues with it.
I can't tell how much experience you have with networking/firewalls in general but a lack of that won't bring you any further by switching to pfSense.
My config probably does factor into some of the issues. To be fair, I've never had to block Internet from a single device before, and the rule seemed backwards compared to my thought process.
If I remember correctly, I started using OPNsense in 2020. Since then, my lab and network has evolved tremendously.
‘Sense’ uses interface to base their rules around. You could use the vlan interface or the wan interface for this.
Yes, that is how networking rules work.
Just an FYI, “your way of thinking” doesn’t apply to pretty much anything. Try learning how things actually work and not assume “your way” is the right way.
I can’t believe I have to explain that.
Not sure why you're being rude for no reason - maybe you need a cup of coffee. I am learning how things work hence the incorrect thought process. Just because you think you know everything doesn't mean you have to put everyone else down for not.
FYI on Fortigates (that I am used to working with opposed to *Sense), there is an incoming (source) and outgoing (destination) interface for the rules, so that's where that thought process originated.
