thanks Synoman,
I am moving from the forum/community of Synology coming here. really got frustrated..
As longtime user of diverse Synology NAS, I feel myself advanced user

but very glad to see some old faces/gurus here...
Currently I am seeking help to run headless browser running in NAS, but it cannot install Firefox or Chrome, and PhantomJS is dying...
On the other side, I would like to learn and explorer the potential of NAS, e.g. how to setup VPN server for WAN access?
