DNS problem when IPv6 Configurator Type set to DHCP
I have set up PfSense 2.2 under Hyper-V and for testing purposes I have two PfSense set up one is under the other.
If I under Interfaces -> WAN sets "IPv6 Configuration Type" to DHCP6 on the firewall which is behind the first one, the second one will have no DNS-servers. If I sets it to none it will have the IPv4 DNS-servers.
If I configure the DNS server under Services -> DHCP Server it will work fine for the clients that are connected to the firewall, but the firewall itself can't download updates while it can't resolve http://snapshots.pfsense.org/FreeBSD_stable/10/amd64/pfSense_HEAD/updates/
Once I set "IPv6 Configuration Type" to none under Interfaces -> WAN the firewall gets the DNS-servers and I can download updates.
The first firewall runs the snapshot from friday Aug 29 and the second firewall runs the snapshot from Monday Sep 1.
I upgraded both firewalls to the Wednesday Sep 03 08:16:45 snapshot and the problem remains.
I now have Tue Sep 16 07:41:09 CDT 2014 versions installed on both firewalls and now it is the other way around. If I do not have DHCP6 activated I do not get any IPv4 DNS servers on the second firewall. Worth noticing is that my first firewall doesn't recieve any IPv6 DNS or IP since my provider doesn't provide that.
Who is your provider?
UPC Cablecom in Switzerland.
The first firewall does though always get the correct DNS. Only the firewall which is behind the first firewall has problems.
Are both pfsense?
Yes, both are pfsense 2.2 snapshots now from yesterday. Both running under Hyper-V 2012 R2.
I now have the below version on both and it seems to work now.
