18.7 Legacy Series / Re: IPv6 default route lost / ICMP6 RA not received
« on: January 02, 2019, 02:54:10 pm »
After rebooting the device, the issue is back.
What I noticed is that the connection would be stable as long as a client would ping to the internet. As I was stopping the ping from that client, die v6 default route on the FW would immediately disappear.
I deleted all VIPs on all interfaces and rebooted the device. Shortly after I am still facing the same issue...
I can see that igb0 still has the public IP assigned but the default route is missing.
Looking into the DHCP log "Services > DHCPv4 > Log file" and filter for "dhcp6c" shows that RENEW replies are being received and the address added to the interface. However, I don't think it is an DHCP issue because the interface does have it's public IP but the routing table does not have that default route set.
