In such an event, disable VPN over ICMP and VPN over DNS functions by appending "/tcp" suffix after the destination hostname. Your payload traffics will be divided and encapsulated into ICMP packets. Awesome! You can activate both VPN over ICMP and VPN over DNS with a simple step. Troubleshooting reaching systems over the VPN tunnel | OpenVPN Run TCPdump and filter for ICMP packets (ping echo requests and echo replies). ctrl+c can be used to interrupt it, but please leave it running for now: tcpdump -eni any icmp. While leaving that program running, go to the connected OpenVPN client (blue computer in our diagram). Open a command prompt or terminal and ping the target system (purple):

I installed this OpenVPN on my server using this. My VPN is working properly without any issues but I wanted to interconnect the hosts which are connected to my VPN. Host A : Host B : VPN Server S : When I ping

Currently I have a openvpn server and client setup with rounting (not bridging) When I try to ping from my client to server ip address it works fine.
