I've made tap work. I'm now working on tun. I have an issue where I
can<br>
ping the server (192.168.101.1) from the client (192.168.101.6) but I
can<br>
not ping the client from the server. This does not make sense to me.<br>

What am I doing wrong?<br>
I see packet going back and forth between the kernel and the client<br>
via ICMP, but when I on the server and try to ping from there, I get no<br>
reply.<br>
