In the web front end you will see two boxes on the dashboard page, one states "Account Balance" the other is "Mined Balance", as long as they are greater than 0 pretty much.
Cheers. How can you see the front end web from a VPS?
I think you do it this way, however im not to sure with the nxt wallet as this is the first time ive used it, but :
Find this file : burst_1.0.0/conf/nxt-default.properties
then scroll to the bottom and find these settings :
#### OLD NRS USER INTERFACE ####
[...]
# Hosts from which to allow NRS user interface requests, if enabled.
nxt.allowedUserHosts=127.0.0.1; localhost; [0:0:0:0:0:0:0:1]; new_external_ip_here; # So grab your ip from ipchicken or which ever way, place it here so the server allows the connection.
[...]
# Host interface for NRS user interface server, default localhost only.
# Set to 0.0.0.0 to allow the UI to be accessed on all network interfaces.
nxt.uiServerHost=127.0.0.1 // Your servers external ip.
You could also do it via making a local proxy (then deny all ips which are not your trusted ones from connecting) using nginx.
However again, and I stress, this might be incorrect.
