IPv6 issues since ER605 v2.0 update to 2.2.4
Since updating from ER605 from 2.2.2 to 2.2.4, I have had IPv6 issues.
Locally, it is an only IPv4 network.
The modem only issues an IPv4 address,
The internet/WAN is set to IPv4 only.
Since the update, every box on the network seems to want an IPv6 address (see below). Despite incoming IPv6 being set to be blocked by default on firmware 2.2.3.
This seems like an extreme oxymoron for the network to enable it, but block all incoming.
This conflict is creating issues espeacilly with cURL. Any update service or serve-server communication that relies on cURL fails.
I have tried to allow incoming IPV6 traffic to the WAN in ACL rules. No affect.
I have tried settings/internet/wan and adding IPv6 options, but all fail. My ISP does not assign an IPv6.
The only work arounds I have found to specificy each addess in a /etc/hosts or to revert the firmware (and not get all future security updates.)
Maybe I'm missing something easy, but I could use some help getting the network back on track.
Thanks!
