Hi,I have the same issue (see my post: https://forum.opnsense.org/index.php?topic=20132.msg93151#msg93151). I now confirmed the issue is with enabling sticky sessions. After a couple of sessions (the amount seems to differ) using any connection to WAN/Internet is impossible. (until you reset the source tracking table). For now I disabled the sticky session tracking and all is working fine. I'm using some fw rules for sites that don't like the effect but this is not ideal.
