ping

Hello, first of all, I want to apologize for my poor knowledge. I hope to receive further instruction

I have the labs setup as shown in the attached photo. OPNsense plays the role of DHCP server and load balancing network.

After setup, I have seen the problem that when users use wifi and connect to the webserver (internal), there is sometimes high latency. It feels like a 1-2 second delay before everything starts loading.

I want to ask what I can configure, or what functions I can turn on or off to improve performance. Or is there a way I can check the problem?

Below are my configuration parameters:
OPNsense setup on Proxmox server.
Network bandwidth: 1Gbps on all wired connections
Card LAN intel 1Gpbs.
Wifi device TP link AX50
The bandwidth I measured with iperf from the user's computer to the webproxy and DNS server is about 400Mbps

I have attached a photo of the ping in the comment

update LAN DMZ rule

update LAN SERVER rule

I changed from PFsense to OPN by hardware issue.
I'm having a problem where OPNsense is blocking connections related to WebSocket. As shown in the picture, from the "Jenkin agent" server, it will not be possible to connect to the "Jenkin master" server. Both of these servers are on different LAN and there is a allow all rule in both.

I also checked the Firewall log but there is no deny log.

I also tried turning off OPNsense and using PFsense (without installing anything else), I can still connect normally.

I wonder if anyone has encountered this problem or can teach me more ways to check the error.
