The 192.168 segment is reserved to private networks so you can not access directly from the internet a node with that address. You need a static IP address in the public network address segment(s). 1 Like Home Categories FAQ/Guidelines Terms of Service Privacy Policy Powered by Discourse, best viewed with JavaScript enabled
