I recently started subscribing to a VPN service, and to check that all traffic is in fact encrypted I used Wireshark. According to this page, the lower, right hand side should be gibberish (from this you probably already inferred that I am not especially tech savvy).
I noticed that these protocols are not encrypted: DNS, SSL, SSDP, TCP, TLSv1.2.
Should not those be encrypted as well?
Using ipleak.net, it seems like there is no leak (not even webRTC, which I removed by a browser add-on).
NordVPN, which I am using, does not seem to allow any special configurations to force all traffic through the VPN tunnel. Is there any way I can do this?
