So, I finally received my FWG, and now it's working as my main router. My previous Asus RT-AX86U is now set as AP and connected to LAN 2 of FWG. FWG is connected to an ONT which provides a PPPoE wan connection. Everything is working fine, ipv4 connection is ok, all my devices are monitored etc etc... EXCEPT, the IPv6.
My ISP provided me with a dual stack connection and it seems like FWG can't handle it correctly. It has to be setup as DHCPv6 with prefix delegation /56. So I enabled Ipv6 in wan connection, set prefix at 56, saved (and rebooted) but i can only see a local ipv6 with no gateway. It's of course unuseful to set ipv6 on the lan interface as long as i'm not able to retrieve the correct ipv6 from my provider along with the gateway. I tried also changing the prefix (60, 64) but nothing changes. There are 2 points that makes me going mad:
1) yesterday, while i was trying all the possible combination, i've been able for a while to retrieve the correct ipv6 and gateway. After a couple of seconds they were gone again
2) in order to exclude ISP problems, i just tried to reconfigure my Asus as main router and...SURPRISE! Ipv6 works perfectly with no issue at all and with a very simple configuration (see the attached image). Using the Asus i was able to pass the ipv6 check (ipv6-test.com)
thus, what's the problem with handling IPV6 in FWG? There are no more option I can play with, given the fact that my isp does not provide a static ipv6, so i just can use dhcpv6...
Guys help me, i don't wanna give up on ipv6 nor i want to use the asus as a router losing all the fwg capabilities which i personally love...
