Is it possible to open a port so that

chili · Wednesday at 23:39

2 ip's can share it?
i have probably not explained that correctly as i am a complete novice at this port forwarding and opening.
Basically i have a raspberry pi and a synology nas i am trying to make port 80/443 open to 2 ip addresses 1 from my nas and 1 from my pi the router is a tp-link

is this even possible, if so please tell me how.
thanks

No.

Does your router have a VPN built-in?

You can do this with a reverse proxy if you're using DNS names but a VPN is more likely going to be what you need

What is the use case?

If it's just to access 2 different devices from outside your network via your IP (Or dynamic DNS), then you just need to port forward one of the devices to different external ports.

E.g.
Port forward the NAS, so that externally you connect to <MY EXTERNAL IP>:8080

The other option is on the Synology you should be able to change the default ports to something other than 80/443 anyway.

The better option as mentioned though, is to use a VPN. Rather than connecting directly to device web pages, and hoping that they are kept up to date to avoid any security vulnerabilities.
