Title: OPNSense blocking legit sites, not idp or web filtering
Post by: norgan on December 08, 2021, 08:48:13 am
Hi all,

I'm working on an issue where several websites won't work. they resolve dns and everything, they just won't connect. It's as if opnsense is blocking them. I can;t see t in routes, firewall, web filtering etc.
If I curl from the console those sites load fast and fine. Anything behind that though has issues. It's only a half dozen sites.

I know this is a bit vague, I'm looking for ideas as to what may be blocking these sites/connections.

Check your MTU and adjust it.
