Port 88 is Open.

[Gaechka 7]

Hello,

 

I used ports scanner service @ https://www.grc.com and it showed that my system has port 88 open (while being connected to AirVPN via UDP-443). Is it normal?

 

I tried to search this forum about this subject but couldn't find any info on port 88. Does AirVPN use this port somehow?

 

Thank you.

Hello!

 

Your test shows that port 88 is open on the VPN server, not necessarily on your system (actually the definitions given by "port scanners" web sites are not accurate, they do not take into account that a system can be behind a NAT on a shared public IP address). Packets to port 88 are not forwarded to VPN clients.

 

Kind regards

Ok! Thank you.

 

Btw, I tried several "port scanners" web sites, they all showed open port 88. But then I used CurrPorts (under Windows) and NetActivityViewer (under Linux) and they both showed NO connections on 88 port on my system - which, as I assume, proves your point that "Packets to port 88 are not forwarded to VPN clients."

 

Thank you again for fast answer.
