I have a residential network with a public IP address running OpenWrt and using Passwall to subscribe to an airport's link. I have set up a service endpoint for SS protocol on the public IP address of my residential network, allowing me to access the internet securely from my own devices outside the network. I am using RC4-MD5 encryption for communication. I do this because the airport restricts the number of devices that can connect at the same time. Does this pose a risk to my account? Can this setup be detected by the airport or other monitoring agencies?
