OpenVPN Support Forum

Hello,

I have a firewall with OpenBSD 4.4 with four clients, tun0, tun1, and tun2 tun3. I now have a new branch and try to set up or tun4 tun5 on I returns the error "Can not open TUN / TAP dev / dev/tun4: No such file or directory (errno = 2)."

There is a limit to the OpenVPN TUN or OpenBSD?

Log Client (Verb 6).

Looks like you need to create this tun4 before you can use it.

In Linux, the command looks like this:
