Hello,

I recently got the 2.2.0 firmware of ER605 which now includes ACL support for IPv6. This is great news, and I was able to confirm that I am able to create IPv6 firewall rules.

However, I found that the firewall rules do not seem to take effect. At this point, I need to point out that I am using "passthrough" mode for IPv6. This is the only way I am able to get internet-routable IPv6 with my ISP's provided ONU.

This might be a stupid question, so forgive me: do firewall ACL rules not work when in passthrough? I know the word "passthrough" implies that firewall rules may be bypassed, but I have read about other routers with a passthrough mode where the firewall still works.

Any information would be helpful. Thanks!
