Hi,
I am using dnsdist 1.4.0-beta1 and am trying to detect queries that are
using a local/experimental optcode. For example, I have the following in
the dnsdist.conf file.
addAction(EDNSOptionRule(65002), DropAction())
and I see the rule in the webserver.

and I sent a query with the ENDS Option and it doesn't get dropped. I know
this because I have a Lua script associated with the pdns recursor that is
processing that specific option.
lua snippit
-- Special Code is in EDNS Option 65002
local specialcode = dq:getEDNSOption(65002)
if (specialcode) then
pdnslog("*************************** Special Code = "..specialcode)
end
Log file Output
*************************** Special Code = BLAH
Any idea on what is going on?
Thanks,
brian
