Hi,



Since a couple of days ago. Bullguard is reporting that an IP address (which is the one my wireless Sky HD box is on) is port scanning about 5 ports every 6 minutes on my PC.



I'd like to know if this is normal? Should a Sky HD box be port scanning my PC? It's only started reporting these in the last few days, but is regular every 6 minutes.

I just need to know if this is a standard wireless procedure that an update to Bullguard has now started to report, or if my Sky Box has started doing something differently.



The ports scanned seem to be 1900, 60366, 62826, 53221 and 56461.



Any help would be much appreciated.

Hello and welcome to our forum!

It should only be required for you to add that as a trusted host.

  1. Open the BullGuard program and click Settings from the top, then Advanced from the top.

  2. Click Firewall and under it click Security.

  3. On the right, click Configure... and in the Trusted Hosts, enter any IPs, separated by a comma (for example: 192.168.1.1, 192,168,1,10).

  4. Press OK to confirm.


If that doesn't work as intended, please contact support so we can get your logs and investigate.

Thank you for the reply.



Those instructions will of course stop the intrusion alerts. My main worry was if this is a normal thing? Do devices such as Sky HD boxes carry out regular portscans?

I also have 3 mobile phones, 3 tablets, a PS4, another PC and a PS3 all on the same network using wireless, and I have never seen a portscan initiated by these devices. There is only this one PC wired to the router.



Before I 'allowed' the Sky HD box, I wanted to be certain it was not behaving in some malicious way.



Thanks.

It is and isn't normal at the same time. It depends on how the device is designed to work.

All devices communicate with at least the gateway, when you first plug them. They need to be told what their IP is in the network at the very least. So when a device from the network does port scans, it's not unusual, as long as they are actually trying to do something with that port, like stream video for example, in which case they state other things to the gateway and to the controlling device (computer) such as which application they intend to connect to.

However, local port scanning is considered safe, as long as you identify which device that is and make sure the behavior is as designed. This is information available in the manual of the device or on the manufacturer website/forum/support documentation.
