For local DNS lookup the local_unbound+named on 192.168.11.254 works but
for any other machine that has 192.168.11.254 as a nameserver nothing is
getting resolved. The very odd part of this is remote used to work but
stopped working all the sudden without any configuration changes to
192.168.11.254 or even logging into it.
192.168.11.254 is up and running and has the following in the named.conf:
listen-on { 127.0.0.1; 192.168.11.254; };
Which is unmodified since the time it stopped working.
Here is the ifconfig for .254:
aryeh@server% ifconfig -a
vtnet0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0
mtu 1500
options=80028<VLAN_MTU,JUMBO_MTU,LINKSTATE>

inet 127.0.0.1 netmask 0xff000000
groups: lo
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
Here is the resolve.conf for the machine that fails to resolve:
search lan.fnwe.net.
nameserver 192.168.11.254
nameserver 192.168.11.1
When queried directly with the host(1) command 254 can look stuff up:
Desktop@neomarx% host google.com 192.168.11.254
Using domain server:
Name: 192.168.11.254
Address: 192.168.11.254#53
Aliases:
google.com has address 172.217.165.142

The uname -a for .254 is:

The ifconfig and uname for the host attempting to resolve google.com is:
