From: Matthew Smith Date: Fri, 2 Mar 2018 17:31:26 +0000 (-0600) Subject: NAT44 - unknown protocols work with forwarding X-Git-Tag: v18.04-rc1~211 X-Git-Url: https://gerrit.fd.io/r/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F40%2F10940%2F2;p=vpp.git NAT44 - unknown protocols work with forwarding If forwarding is enabled, inbound packets on an outside interface should not be dropped and instead pass on to the FIB lookup. This works for TCP and UDP but not other IP protocols. Enable it for unknown protocols.
