@dc42 tested, it work nice.
Great job.

@dc42 config.g duet.txt

I try now disable telnet and ftp. DWC is working for me
Thx.

@dc42 "CORS disabled"?

@dc42 Sorry, over my lan and the ping is ok but did not work DWC Telnet or FTP, the machine and panelDue work nice.

I have tested on 3 Duet2 Wifi that are in DWC 3.4.3, wifi firmware 1.2.7 and RRF 3.4.2, when updating with the new firmware 3.4.3, it does not allow remote access (web, ftp, telnet) (if there is ping and open ports) panelDue shows everything correct. With the Duet2 ethernet and the duet3 Mini5+ wifi I have had no problems, I have downgraded the duet2 wifi to 3.4.2 and they work fine.
Now I am testing with a spare board and a new MicroSD with the minimum configuration and using PanelDue to change the firmware since I lose communication as soon as I install the 3.4.3 file.
I have tried to downgrade the WifiServer to 1.2.6 with identical results.

@dc42 Ok, Thx. https://forum.duet3d.com/topic/30067/loss-remote-access-to-duet2-wifi-after-firmware-3-4-3-upgrade

@dc42 The Duet2 Wifi with the new firmware 3.4.3 does not allow remote access (if there is ping and open ports) With the Duet2 ethernet and the duet3 Mini5 wifi I have not had problems, I have downgraded the duet2 wifi to 3.4.2 and they are doing well. Is a bug?
