External port scan results change after a few days of uptime ERL.

HI,

 

I was curious if anybody else has seen external interface ports show open that are closed after a few days of uptime.

 

My testing is using the Shields UP scan site (www.grc.com) to check for open ports on my external interface.  On a fresh reboot and tested for a number or hours / day one of uptime  the test all show closed or stealth as they should for the ports 1 - 1023.  After 3  or so days of uptime I start seen port 443 and 22 respond as open.  

 

Nothing has changed on the config and if I restart the router they show as stealth again.  I will try to rescan daily to see if it is anything that is replicated over time...

 

Any thoughts?

Thanks in advance..
