HA sync functionality question

[greg124816]

Ok, I haven't really looked and definitely haven't dug into the code to find the answer myself but, I'm curious about the actual behind the scenes process of changing a simple firewall rule in a HA pair (changing from the master of course).

Ultimately I'm searching for the reason I see a 30-60 second delay in "applying" a rule change.

In the course of double and triple-checking things I have a simple pass-rule where I click on the green/gray triangle to "enable/disable" and of course it produces the "Apply" button up top. But, what I've found is that after I click the green triangle to either enable or disable the rule, it propagates to gui on the HA peer (without ever clicking apply).

I have monitored the active pf ruleset before/after enable/disable and before/after clicking the Apply button. I need to redo the testing because I am not sure what I saw. I think sometimes I wasn't waiting long enough between checks and a previous click of the Apply button took effect on the active pf rules.

Anyway, what I'm most confused by is that when i click to disable/enable the rule, the change propagates to the web gui on the peer in a couple seconds and local page refresh is complete. When I click Apply, it takes over 30 seconds for page refresh to finish but I see all the xmlsync traffic (via tcpdump) occur within a couple seconds.

If i disable the HA Sync, of course there is no delay in page refresh after apply.

I've gone over my entire config, compared to other setups and online examples. I'm not new to the opnsense/pfsense HA setup, I've had one running at home and a couple at work since the pfsense v1.x days.

I haven't not had time to dig into the web gui code to figure out what's supposed to happen as far as the xmlrpcsync and filter reload etc on local and peer. I'm hoping someone knows and has the time and patience to tell me what's supposed to happen.

Thanks!
