if ISP blocked, if I telnet to my WAN IP,it must show 'cannot connect for block 21'?
But now, when I telnet to my WAN IP,it no any err,just have a blank screen with a cursor. (look like it accepted by Tplink,But no FTP Hello wording...'
If I telnet by LAN,it will have FTP 'Hello' wording..
thanks |
