Browser freezes when loading 2000+ rows of firewall rules
-
WebGUI freezes the web browser when trying to load the firewall rules and NAT rules page with 2000+ firewall/NAT rules. The pages will load after ~3 minutes if we chose to wait.
pfSense version: 2.4.5-RELEASE-p1
As a workaround, Disabling the dragging option in System -> General Setup resolves this freezing issue.
Is it a known issue already or need to be raised as an issue?

Just out of curiousity, what are you doing with 2000+ rules?

I join----- @heper
what is the size of the network, that requires such a large number of rules?yeah another question what kind of hardware handles this amount of rule?

@ekanthan it seems that you need to use aliases (IP/host/ports) to reduce it to some reasonable number
See https://docs.netgate.com/pfsense/en/latest/book/firewall/aliases.html

I was stress-testing pfSense in a VM.
Regardless of hardware spec, this is a client-side issue. So, I raised it for discussion. -

SOHO category hardware needs time to load and handle the lot of rules....
yes, this can cause temporary GUI unavailability (it depends on the resources)
as @viktor_g suggested, many rules can be simplified using aliases

@DaddyGo As I mentioned earlier this is a client-side issue, the server provides the response in seconds, But the client-side DOM rendering and processing makes the browser to freeze as the page tries to restructure 2000+ rows to sortable drag and drop elements. It takes ~3 mins only on browser(client) end.
Disabling that option resolves the issue and the page renders in seconds.

Right, this is System / General Setup option:

Well, as long as it's easily disabled, I don't think I'd consider it a bug. But that's just me.

That is the reason that option exists. It's a client browser issue, not a firewall bug, and that option helps your browser cope with large rulesets.
