IPV6 Recursive DNS on the fortigate
I have configured recursive DNS server on my fortigate. Straight forward config
config system dns-server edit "lan" set mode recursive set webfilter-profile '' next end
It works great on IPv4 on my LAN.
Here is where I am having issues. I have IPv6 configured on the LAN interface as well. all my LAN clients can do IPv6
Since my ISP is not IPv6 capable, I have NAT64 configured. Also I have a IPv6 tunnel to a tunnel broker. Both works without issues.
config system sit-tunnel edit "HE" set destination xx.xxx.xxx.xx set ip6 xxxx:xxx:xx:xxx::2/64 set interface "wan" next end
For some reason if I use DNS recursive server on the fortigate on IPv6, queries are constantly timing out. sometimes it works.
My questions:
1. Does ipv6 recursive DNS server works on fortigate? (current firmware 5.2.5)
2. Anyone setup ipv6 on the fortigate with full config and have a sample setup scenario?
3. Any troubleshooting tips?
