Re: [vpp-dev] NAT44 for TCP/UDP

Hi Ashwini, I will look into your issue. But for reference I would advise against using a combination of inside interface and output-feature. OUTPUT-FEATURE or in other words output interface already contains nat44-inside node. Output-feature does postrouting - after ip4-lookup node decides which
