VPN over ICMP

[GoodA]

Такая ситуация: надо подключится к удаленному ПК через VPN, но вход в эту сеть возможен только по ICMP может кто подскажет как это реализовать? Можно ли прокинуть VPN по ICMP???

ICMP это диагностический протокол. Как через него вход вообще возможен?

VPN over ICMP, and VPN over DNS (Awesome!)
A few very-restricted networks only permit to pass ICMP or DNS packets. We don't know the reason. On such a network, TCP or UDP are filtered. Only ICMP and DNS are transferred.
In order to make it possible to establish SoftEther VPN client-server session via such a very-restricted network, SoftEther VPN has the "VPN over ICMP" and the "VPN over DNS" function.
This function is very powerful to penetrate such a restricted firewall. All VPN packets are capsuled into ICMP or DNS packets to transmit over the firewall. The receiver-side endpoint extracts the inner packet from the capsuled packet.
This is very useful for exploiting public Wi-Fi. Some public Wi-Fi can pass only ICMP or DNS packets. They filter TCP or UDP packets. If you have a VPN Server installed on your home or office in advance to go outdoor, you can enjoy protocol-free network communication by using such a restricted network.
VPN over ICMP, and VPN over DNS are implemented based on ICMP and DNS protocol specifications. However, they sometimes behaves irregularly. It might causes memory-overflow or something problems on the "buggy routers" on the network. Some routers might reboot because of these problems. It might affect other users of Wi-fi around you. In such an event, disable VPN over ICMP and VPN over DNS functions by appending "/tcp" suffix after the destination hostname.
