[Pdns-users] Unable to filter Domains - Recursor 4.x behind dnsdist

I am running an alpha release of Recursor 4.x for the domain filtering
option. After configuring the lua scripts I was able to test a successfull
query from the Recursor Local Host by adding it into the IP Filters file.
However, when I try from my remote host the filter does not work. I am
running the Recursor behind dnsdist with "useclientsubnet" directive
enabled. I confirmed the LB is sending OPT packed with the EDNS client
subnet embedded into the DNS Query.
I suspect Lua is not parsing this data properly and parsing all traffic from
the IP source being that of the Load Balancer. Should I be using a
"getEDNSOption" to explicitly tell the Lua script to look for the EDNS
client subnet in order to properly match my filters?
Any help is greatly appreciated!
Here is a snippet of my action script:
if(not adservers:check(dq.qname) or (dq.qtype ~= pdns.A and dq.qtype ~=
if(not filterset:check(dq.remoteaddr)) then
"fake."..dq.qname:toString().." fake."..dq.qname:toString().." 1
7200 900 1209600 86400",
