IPV6 Recursive DNS on the fortigate
I have configured recursive DNS server on my fortigate. Straight forward config
config system dns-server
set mode recursive
set webfilter-profile ''
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
set destination xx.xxx.xxx.xx
set ip6 xxxx:xxx:xx:xxx::2/64
set interface "wan"
For some reason if I use DNS recursive server on the fortigate on IPv6, queries are constantly timing out. sometimes it works.
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?
