I'm trying to obscure a normal http soap call to a device so that it doesn't use port 80. My only reason why is that the device doesn't do https.
So I picked a random port (43) to address an intermediate server to send the message and discovered that the port is blocked on iOS and android.
Is there a list that is readily accessible?
List of TCP and UDP port numbers (wikipedia)
Port 43 is WHOIS protocol.
A port number in a high range is usually safe, say a number over 10000. Port numbers are 16bit numbers so they go up to 65535.
