Hello fellow everyone,
I am seeking for guidance/help.
As my ISP does not support IPv6 I decided to use HE tunnelbroker.net.
My current network setup would be:
Internet --> Mikrotik router --> 2x OPNsense HA firewalls --> LANs
LANs:
192.168.10.0/24
192.168.11.0/24
192.168.12.0/24
and so on.
On Mikrotik router I have added the routable IPv6 and advertise it.
On OPNsense I use "SLAAC" on IPv6 at WAN interface.
For my internal LAN interfaces I use "track" with WAN interface.
So far my devices behind OPNsense do get IPv6 address but connectivity is a pain.
Sometimes I can ping remot IPv6 hosts - sometimes I can't.
After a restart OPNsense is using it's own local-link address as a default gateway?
It seems it's nearly impossible to get a proper setup with OPNsense and IPv6 for my subnets.
Can someone enlight me?
