Windows 10's Norton 360's VPN component encounters an error when I try to connect it through a certain sub-net: 809.
But it does not occur in Mac OS 11, and there, it works.
It seems to be due to the effective absence of Universal Plug'n'Play protocol on the router, which I cannot configure elsehow.
1/2) So it seems to be due to the version respective to the OS, but I'd like to know if it is true or wanted.
There are some possible solutions here: https://support.norton.com/sp/en/us/home/current/solutions/v135460781?product=Norton%20360&version=126.96.36.199&plang=sym:FR&layouttype=ESD&buildname=Retail&heartbeatID=9EF13C67-697E-495E-A0F3-8BCDDC9F0AD3&eapenabled=false&env=prod&vendorid=1000&plid=866&plgid=41&skup=21416514&skum=21376863&skuf=90001202-FA&endpointid=9EF13C67-697E-495E-A0F3-8BCDDC9F0AD3&partnerid=1000&lic_type=16&lic_attr=17059858&psn=GWF9GD4DMV6C&puid=5039&templatecat=SBU_W_1000_5039_N360DSP_ESD&schemacat=SBU_W&schemaver=188.8.131.52&olpchannel=SESD&remdays=712&osvers=10.0&oslocale=iso:CHE&oslang=iso:FRE&os=windows
, but (2/2) I guess that it can be solved transparently, as in Mac OS?
