Define the extractor outside the function InDirectnip_proto.dissector,
like this:

ip_addr_f = Field.new("ip.src")

Inside the dissector function you fetch the value using this
extractor, something like this:

  if (ip_addr_f()) then
    print(tostring(ip_addr_f()))
  end

Sure, just add more udp_table:add()
