SoftEther VPN User Forum

Is it possible for you to have an ICMP protocol besides UPD and TCP?

With SoftEther VPN Server Manager you can via

Encryption and Network > VPN over ICMP / DNS Settings > Enable VPN over ICMP Server Function

It is also noted on the same screen that it requires VPN Client / VPN Bridge internal version 4.0 or greater.

By default VPN over ICMP or DNS are disabled and is noted to be recommended when the firewall is blocking TCP/IP connections.

I am unsure how is one able to connect to a SoftEther VPN server via ICMP using SoftEther VPN Client Manager.

I tried blocking the TCP/UDP (and only UDP) in my firewall, and the client won't ever connect to the server.. This option is very interresting and the devs should allow to be able to force for testing purposses in a future update.
