The HTTP, HTTPS, SMTP, POP3 and Microsoft Exchange protocols all use TCP by default. UDP is a good choice if the majority of the traffic generated by your Mobile VPN with SSL clients is TCP-based. If this happens enough times, users might notice the poor connection performance. With slow and unreliable connections, TCP error checking timeouts cause VPN traffic to be sent more and more slowly. Because the majority of traffic that passes through a VPN tunnel uses TCP, the addition of TCP error checking to the VPN connection is redundant. The additional latency is caused by error checking that is part of the TCP protocol. Normally TCP works as well as UDP, but TCP can be significantly slower if the connection is already slow or unreliable. If the access site uses proxies, the SSL VPN traffic is likely to be denied because it does not follow standard HTTP or DNS communications protocols. If the access site uses packet filters, the SSL VPN traffic should pass. For example, change the port and protocol to UDP 53 or UDP 1194 and determine whether users can connect. If users cannot connect to the Firebox over TCP 443, one possible solution is to change the port or protocol. By default, Mobile VPN with SSL operates on the port and protocol used for encrypted website traffic (HTTPS) to avoid being blocked.Īnother main advantage of SSL VPN over other mobile VPN types is that you can change the port as well as the protocol (UDP or TCP). Other mobile VPN types on the Firebox use specific ports and protocols that are blocked by some public Internet connections. If you need to change the default port or protocol for Mobile VPN with SSL, we recommend that you choose a port and protocol that is not commonly blocked. #Changing ipinator vpn ports how toHow to Choose a Different Port and Protocol Mobile VPN with SSL traffic is always encrypted with SSL, even if you use a different port or protocol. If you have an additional external IP address that does not accept incoming TCP port 443 connections, you can configure it as the primary IP address for Mobile VPN with SSL.
