Change port 80 outside access?

Is there any way to change port 80 to be able to access from an external network to a wifi duet ?.My problem is that I have 3 duet wifi and I can only access one of them by forwarding ports and I do not know how to put the others.
Is there any way to change port 80 in the other wifi duet ?.

Yes you can, check M586 :
M586 P0 S1 R20000 ; Set Port 20000 for HTTP

Most routers allows forwarding any port to any port. So you can map:
81 to port 80 on first duet
82 to port 80 on next duet
and so on.

However... I personally would NEVER "forward" a device such as a Duet to the public internet.
Use a reverse proxy that requires authentication, etc.
Yes please do not put a Duet on the open internet. If you need to access it remotely please use a VPN

As an alternative to running a VPN or reverse proxy, you can set a password on each of your printers
- set a password on each printer using the M551 command in your config.g
- set each printer to have a fixed internal IP
- set port forwarding, preferably use an obscure port - IE something like port forward 7193 from external or some other random port to your internal DUET port 80, then on 2nd printer use port 7194 etc
I do this for for my 3 printers, along with a webcams on each so I can monitor prints when I am at work using my pc or my phone when I'm out for dinner etc, I need to supply the password to do anything like stop the printer if I need to etc.
Sure VPN / SSH / Reverse Proxy and other methods are providing more robust security but they add complexity and steps to monitor your prints from outside. using an obscure port along with requiring a password is enough for me, I'm in the "I just want to get it working simply and with at least some form of password protection" camp

Port scanners don't care how obscure a port is. Just sayin.
@crash69 the password on the duet is not intended to provide security against a determined attacker, also when you login, because the duet is not using https, that password is not sent securely. This can just stop a casual connection from someone curious. I must repeat this please do not put Duets on the open internet (or a large uncontrolled intranet like a university). If you have a use for controlling them remotely then either provide a VPN into your local network, or remote connect into a local PC and control them from that.
