In KEXT, I changed the target connection information using the socketFilter.
ex) run program > connect network > check destination ip and port > if need to change then change destination ip and port
Which features can be used to change destination access information in MacOS Catalina's Network Extensions?
I need your help.
What is your end goal? Are you building a Content Filter application or are you building an App Proxy application? Can you tell me a little more?

I Want to make like below
1. user try to connect to server01
2. network extensions -> check connect destination is server01
3. then change destination (server01 -> server02)
----------
ex) user -- try connect --> server01 then
user -- connect address change --> server02
thank you
Based on what you have described it sounds like you want an App Proxy or possibly a Transparent Proxy. When your NetworkExtension has a new flow to handle, you can perform logic on it and decide how to handle or discard it. This then leads you down the path of proxying a flow to a new endpoint if needed or letting it continue as normal. See NEAppProxyProvider for more information to see if this fits your application requirements.
