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.
