Summary - Software flow offloading possibly conflicting with ipv6 or firewall
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Low
Priority - Very Low
Reported Version - openwrt-21.02
Due in Version - Undecided
Due Date - Undecided
Details - Supply the following if possible:
 - Device problem occurs on
 - Software versions of OpenWrt/LEDE release, packages, etc.
 - Steps to reproduce

 The problem is on a Raspberry Pi 4 running OpenWrt 21.02.0-rc3, i noticed that with software flow offloading enabled (hardware flow disabled) that sites largely based on video/images such as instagram and youtube were very slow to load, would take multiple refreshes to load or wouldn't load at all, sites that were mainly text worked fine, after trying different settings i eventually noticed that going to Luci>Network>Firewall>Zones>Wan>Advanced Settings and setting Restrict to address family ipv4 solved the problem. Switched back and forth between Restrict to address family ipv4 and ipv6 and ipv4 only a few times to make sure it wasn't just a fluke, but the problem reappeared every time Restrict to address family ipv4 and ipv6 was set and went away every time Restrict to address family ipv4 was set, so i don't know if the problem is with ipv6, firewall or the sites themselves, but it seemed worth reporting. There isn't any problem with software flow offloading disabled.
