Hi all,

I just ran a port scan on my home router (EdgeRouter X) and there appears to be a service running on port 9999 named 'abyss'. Does anyone know what this is?

ShieldsUP! shows port 9999 as 'stealth' on the WAN side.
 

Presumably it's some internal configuration web server?
 
A backdoor? A way (once securely configured) to access your router's configuration remotely?
 
You are correct.
I once used a Canon printer on my network, but it is no longer connected. Would port 9999 remain open even though the printer is no longer on the network?

No NAS on the network. The only devices on the network are a desktop, laptop, android phones and some raspberry pi's.
