    Port - 57596 - What is it?

    Hi All

    Quick question - looking at my router logs I see a lot of incoming UDP connections to my connection's public IP to port 57596

    anyone know what that PORT is used for and whether its anything to be concerned.

    Hi,
    if is a free port number so no official service bound to that port. If you do not have a port forward for this port it cannot do any harm.

    Possible causes: script kiddies scanning scanning IPs to look for ports of malware. If you get a new IP each day, like I do, perhaps the last owner of this IP did something with this port.

    ciao

    Definitely no port forward to it set by me.

    I see incoming connections from multiple IP addresses every hour - which is what raised the alarm.

    Try doing a port scan yourself to make sure its not open.

    For info: Shields Up will scan for open ports. Select on the second page 'All service ports' to scan ports in the range 0 to 1055
    Code:
    https://www.grc.com/shieldsup
    For port 57596 you have to select 'look-up specific port information' option in the second page and then type in the port number for scanning.

    Doing the scans the port shows up as closed (or should I say stealth) - however the router logs say otherwise.

    Hi,
    your logs say that someone tries to connect. Why shouldn“t anybody try to connect to a closed port? As I said your router is connected to the open internet and there is always someone who is trying to knock on the doors of some router to see if there is an entry point.

    ciao

    I agree with Trial. The router is logging the attempts but the port is closed. I used to see this all the time.

    what triggered my attention was that the router logs shows that the connection is being ALLOWED.

    I can only think its something on your internal network thats using this port. What have you got connected on your internal network?

    probably some game that you play is using this port.See that also on my router when son is playing games like game of trones.These ports open only during game sessions.

    Having forced a Public IP change I am no longer seeing those incoming connections. Must be something related to the previous user of that IP.

    Which would be using UPnP.
    Basically it allows any internal client to tell the router to allow an external port (usually UDP for games) so that you can interact with multiple external clients. There may be an option somewhere on your router/modem to allow/disallow it (but if you disallow it presumably network games won't work...)
