Hello all, I'm not a fan/user of any social media at all hence I dint noticed this problem before, unfortunately with the nowadays marketing trends I have to sin and get involved with "WhatsApp/Instagram" just to get in touch with the "Solar Energy" business and found some problems when loading content from such sites.
Been using OPNSense since version 16.x and never had any problem on my small homelab/office network other than recently found that "Meta" child websites/apps partially work when pass through OPNSense, the webpage(Instagram) load but the content is blocked, i.e. images/videos etc but text, for WhatsApp chats is the same the media content does not load and have to turn off Wi-Fi and use cell data in order to view the images/videos, however if I connect the Linksys access point directly to the ISP cable modem the Meta websites/Apps works on all clients as intended but that's definitely not an option.
I did search the web/forums in this regards but just found some repetitive advice about "Enable syncookies" in which I've tried in either "never/always/adaptive" without success, I really hope some with knowledge in this case can bring some viable advice, other than the easy route on leaving host(s) vulnerable to DDoS.
System: (moved to Bhyve VM)
i5-2390T + 8GB RAM, 160GB HDD
HP Pro 6300SFF(WAN) + HP NC360T(LAN/OPT)
Versions:
OPNsense 25.1.4_1-amd64
FreeBSD 14.2-RELEASE-p2
OpenSSL 3.0.16
Network:
ISP --> OPNSense --> Linksys-AP --> Clients
Regards!
Edit:
Here is an example of the Meta site loading but without media content, it gets stuck in a connecting loop to ...fbcdn.net.

Here is a similar case in this regards in r/opnsense without proper solution, and again the OP Update/Solution is not an option for me. ;)
