Changing upstream TCP packets on the fly

Open drasko opened this issue 6 years ago • 7 comments

I am using OpenResty as a TCP (stream) proxy. I have been capable to read TCP packets using reqsock:peek and preread_by_lua_block directives.

However, would like to change certain bytes of the TCP packet as it flows though the proxy, so that the service behind gets a changed packet.

Is this possible to achieve with ngx_stream_lua_module and how?

Any updates on this? Is something like this possible?
