I flashed wr740v4 finaly with OpenWrt but cant set port

Is there any way to set port on unoficial minimal firmver for tplink wr740v4

Questions about third-party builds should be sent to that third party not here.

There is no longer official support for the WR740 due to it having insufficient flash and RAM.

"Tiny" models are not good for beginners because it's constantly necessary to work around having small flash and RAM instead of being able to use the OS freely.
