I'm getting started with knot resolver and am a bit unclear as to how this
config should be structured.
The result I'm looking for is to forward queries to resolver A if the
source is subnet A; unless the query is for the local domain if so then
query the local DNS.
I've been working with the config below to accomplish this. However I'm
finding that this config will if the request does not match the local
todname and will use root hints if not but will not use the FORWARD server.
Ultimately, this server will resolve DNS for several subnets and will
forward queries to different servers based on the source subnet.
Would someone mind pointing me in the right direction on this, please?
for name, addr_list in pairs(net.interfaces()) do
net.listen(addr_list)
end
-- drop root
user('knot', 'knot')
-- Auto-maintain root TA
modules = {
'policy', -- Block queries to local zones/bad sites
'view', --view filters
'hints', -- Load /etc/hosts and allow custom root hints
'stats',
}
-- 4GB local cache for record storage
cache.size = 4 * GB
--If the request is from eng subnet
if (view:addr('192.168.168.0/24')) then
if (todname('localnet.mydomain.com')) then
policy.add(policy.suffix(policy.FORWARD('192.168.168.1'),
{todname('localnet.mydomain.com')}))
else
view:addr('192.168.168.0/24', policy.FORWARD('68.111.106.68'))
end
end
