Mac OS Connection issue

[fred]

It seems VPN Gate is not working on macOS 10.12.4

I also use Mac OS 10.12.4 (sierra) and VPN connection seems not working.
VPN connection by L2TP over IPsec says "connected" .
However, VPN Gate web page shows the same IP address as I use it without VPN.
( But , web browsing speed of various sites seems to become slower when "connected".)
I changed the server but the situation din't change.

If I use vpn thru CISCO, the IP address shown in the VPN Gate page changes
as expected.
