again, there is only one direction ">" from 10.30 to 179.xx
we don't see any answer on your post ( from 179.xx to 10.30 )

So what does that mean? The DELAY banner is supposed to show when the delay happens? Or does it mean that all the traffic under it is delayed? You seem to have some FIN and RST packets there which will definitely interrupt a connection.
What is the purpose of the site? Do you have multiple WANs?
-
The banner I placed to show the part where the longest page load delay occurs.
We are a branch of a university and the site is of another branch for student access. Each branch office has its own independent infrastructure.
We tested OPNSense and access is normal.We only have one WAN
-
Do you have any packages installed, like Squid, pfBlocker, Snort, Suricata...?
-
Thanks. I disabled pfBlocker and the issue is resolved

pfSense troubleshooting 101 ...
. Anytime you have connectivity issues with a pfSense installation and you have any packages installed, disable all the packages first and then see if the problem disappears. Odds are it will. After that, you know the core pfSense setup is fine. So then start enabling the packages one-by-one to see which one is the cause of the issue.Suricata, Snort, Squid and pfBlocker can all be potential problem makers. Suricata, Snort and pfBlocker rely on third-party inputs (rules for Suricata and Snort) and IP lists (for pfBlocker), and any of those third party tooks can have bad data in them that cause false positives.
