Router嘅弊端在於硬件速度實在係太慢,唔好忘記VPN係透過加密協議在服務器同客戶端建立起一條加密通道,硬件速度越快,VPN連接嘅加密同解密速度就會越快,即使同樣係行OpenVPN,虛擬機都會比Router快好多,5蚊美金嘅配置係20GB SSD硬碟同埋1GB Ram, 家用Routuer嘅加密同解密速度邊度比得上?我以前都係用TP Link set PPTP VPN,下載速度最高先至去到500KB/秒,而家用虛擬機OpenVPN,Youtube視頻最高試過8-10M/秒緩衝。你話個分別大唔大?
"次次都連得上wor" - being able to connect doesn't mean the connection is secure or stable. Very frequently the initial connection is ok but got disconnected in a few minutes; or the connection is patent but no browser data could get through.
OVPN is known to be very easy to detect and block.
