[sr-dev] External Nat Ping / no 2nd via found

Hello, Would it be advised to simply comment out this error when doing nat-pinging externally to Kamailio? It seems the error is a result of Kamailio receiving a reply where no transaction is found (which is because the OPTIONS request and or "nat pinging" is being handled external to Kamailio). Which results in quite a bit of logging for each non transaction matching reply. Thoughts? Solutions? Thanks as always in advance! Sincerely, Brandon Armstead
