If you want to make a VPN connection between SoftEther VPN Client / Bridge and SoftEther VPN Server, but if TCP and UDP packets are prohibited by the firewall, then you can encapsulates payloads into "ICMP" (as known as Ping) or "DNS" packets. This function can realize a VPN connection by using ICMP or DNS even if the firewall or router blocks every TCP or UDP connections. VPN over ICMP / VPN over DNS functions are designed to comply standard ICMP and DNS specifications as possible, however it sometimes has a behavior not to fully comply them. Therefore, few poor-quality routers may be caused a memory-overflow or something troubles when a lot of ICMP or DNS packets are passed, and such routers sometimes freezes or reboots. It might affects other users on the same network. To avoid such risks, append the suffix "/tcp" on the destination hostname which is specified on the VPN-client side to disable VPN over ICMP / DNS functions.

If your SoftEther VPN Server is placed behind the NAT or firwall, and by some reason you cannot use NAT Traversal function, Dynamic DNS function or VPN over ICMP/DNS function, you can use VPN Azure Cloud Service. SoftEther Corporation operates VPN Azure Cloud on Internet. After the VPN Server makes a connection to the VPN Azure Cloud, the hostname "abc.vpnazure.net" ( "abc" is a unique hostname) can be specified to connect to the VPN Server via the VPN Azure Cloud. Practically, such a hostname is pointing a global IP address of one of cloud servers which are operated by SoftEther Corporation. If A VPN Client connects to such a VPN Azure host, then the VPN Azure host will relay all traffics between the VPN Client and the VPN Server. VPN Azure is disabled by default. You can activate it easily by using VPN Server Configuration Tool.

1.6. UDP Acceleration 1.6. UDP Acceleration
SoftEther VPN has the UDP Acceleration Function. If a VPN consists of two sites detects that UDP channel can be established, UDP will be automatically used. By this function, throughput of UDP increases. If direct UDP channel can be established, direct UDP packets will be used. However, if there is something obstacles such as firewalls or NATs, the "UDP Hole Punching" technology will be used, instead. The "UDP Hole Punching" uses the cloud servers which SoftEther Corporation operates on Internet. UDP Acceleration can be disabled anytime by setting up so on the VPN-client side.
