Running Ubuntu 18.04 LTS, and I am trying to configure Bind as a DNS server, for my home lab, as some of the software (VMware) requires DNS to run.
I have the reverse lookup working with issue, but forward lookup returns 0 answers. nslookup also fails to find the domain, and if I change this server to use itself for DNS in "/etc/resolv.conf", it has no network connectivity.
the contents of my bind configs are
named.conf
include "/etc/bind/named.conf.options";
include "/etc/bind/named.conf.local";
include "/etc/bind/named.conf.default-zones";
named.conf.options
acl "trusted" {
10.0.1.90;
10.0.1.55;
10.0.1.57;
10.0.1.58;
10.0.1.100;
};
options {
directory "/var/cache/bind";
recursion yes; # enables resursive queries
allow-recursion { trusted; }; # allows recursive queries from "trusted" clients
listen-on { 10.0.1.90; }; # ns1 private IP address - listen on private network only
allow-transfer { none; }; # disable zone transfers by default
forwarders {
10.0.1.1;
8.8.8.8;
8.8.8.4;
};
dnssec-validation no;
auth-nxdomain no; # conform to RFC1035
listen-on-v6 { any; };
};
named.conf.local
zone "myhome.lan" {
type master;
file "/etc/bind/for.myhome.lan";
};
zone "1.0.10.in-addr.arpa" {
type master;
file "/etc/bind/rev.myhome.lan";
};
for.myhome.lan

checking everything looks good
root@dns-01:/etc/bind# named-checkconf
root@dns-01:/etc/bind# named-checkzone myhome.lan for.myhome.lan
zone myhome.lan/IN: loaded serial 2018052102
OK
root@dns-01:/etc/bind# named-checkzone myhome.lan rev.myhome.lan
zone myhome.lan/IN: loaded serial 2018052101
OK
but dig and nslookup do not work
root@dns-01:/etc/bind# dig -x 10.0.1.90

I am banging my head against a wall, any help in identifying the problem would be greatly appreciated!
