Problems with unbound

[Andrea Brancatelli]

Hello everybody, 

we're suddenly having problems with unbound on almost all of our servers
and I cannot really understand why. 

To make a long story short, we use this forward.conf: 

root at dbengine-ent-rm-01:/var/unbound # cat /etc/unbound/forward.conf
# This file was generated by local-unbound-setup.
# Modifications will be overwritten.
forward-zone:
name: .
forward-addr: 8.8.8.8
forward-addr: 8.8.4.4 

Enabling this: 

 auto-trust-anchor-file: /var/unbound/root.key 

in /etc/unbound/unbound.conf gives me this: 

root at dbengine-ent-rm-01:/var/unbound # host update.freebsd.org
;; connection timed out; no servers could be reached 

simply disabling that line gives me this: 

root at dbengine-ent-rm-01:/var/unbound # host update.freebsd.org
update.freebsd.org is an alias for update5.freebsd.org.
update5.freebsd.org has address 204.9.55.80
update5.freebsd.org has IPv6 address 2001:4978:1:420::cc09:3750
update5.freebsd.org mail is handled by 0 . 

What's going on? 

root at dbengine-ent-rm-01:/var/unbound # freebsd-version
10.2-RELEASE-p13 

Thanks.
