Ports which are to be opened for L2

to check whether ports are open you should do the following actions:

1. press win+r buttons. type 'cmd'. in the appeared window type
'telnet 109.105.156.11 17453'.
if you see black screen or incorrect character set ports are open.
do the same for commands
'telnet 109.105.156.11 7777'
'telnet 109.105.156.12 17453'
'telnet 109.105.156.12 7777'
'telnet geo.l2.eu 2106'
'telnet cdn.inn.eu 80'
and
'telnet frostsecurity.net 80'.

2. if you see on the screen "'telnet' is not recognized as an internal or external command, operable program or batch file' you should turn on telnet feature. to do this click start button. find 'control panel'. in the appeared window select 'programs and features'. in the left side of the window click 'turn windows features on or off'. find 'telnet client' in the list and select its check box. click 'ok'. after that follow paragraph 1.

3. if you see 'connecting to ip - address...could not open connection to the host, on port : connect failed' it means that ports are closed and you have to contact your provider.
