streaming issues

[petersk]

I installed 20.1 of OPNSense on a Xeon 4 core with Two NICs (HP ML110). Everything seemed to be working right, but when I try to stream netflix or amazon prime, it will not stream.  It's really slow loading an Netflix goes to about 24% buffering and then errors out. Any thoughts on tuning to get better performance, or skipping the firewall entirely for those sites. Set up is as you can imagine:
  _____________

   _____|______
   | WAN NIC     |
   |  opnsense    |
   | LAN NIC       |
   |___________|
            |    NAT to my network


Any help would be wonderful... I'm back to using my Netgear router because we cannot stream.
