Re: [lwip-users] lwip tcp hangup

That’s true. You need a public facing IP to do the scan.

I can see that after scan I have at least 6 pcb staying for forever in CLOSE_WAIT state even there is no communication and after that I can not access the web server as there is no connection after that. I can still ping my device successfully.

Could you please elaborate more on this? I'm interested in hardening the httpd (or whatever goes wrong there), but it seems you have to connect an lwIP device to a public IP address to do that scan. Is this correct or is there a tool available for download to do this scan?
