</div>Ok, it looks like the tinc-up script worked fine. Can you show me the output of<br>
"route -n" on both VPN servers?<br>
<br>
Are you using iptables or other forms of firewalling? Also, you can start tinc<br>
with the extra options "-d5 -D", which will cause it to run in the foreground<br>
and log almost everything that is going on. Try to ping while you are running<br>
tinc like that, and see what it logs.<br>
