Why are some websites especially slow to open（OPNsense 19.1.3)

[agh1701]

Fixed in 19.1.4:
  o firewall: fix validation regression in outbound NAT introduced in 19.1.3

I UP TO 19.1.4.
The problem feels like it's still there, and I only have one NAT policy that allows all of those

The reason was found. Is the superior router configuration problem, thanks All

Glad you have it sorted but just wonted to say that i had issues with HTTPS websites like google and duckduckgo but it turns out that unticking block bogon networks worked for me however i have no idea if is because i have a ISP VDSL2 router within 192.168.50.0/24 subnet what is behind the opnsense box and it seems that my VDSL2 ISP router is broadcasting multicast on LAN for IPTV.
