I'm trying to setup multiple layers of IPIP tunnels on a FreeBSD system (destined to Cisco routers). I have what I believe is the correct setup on the FreeBSD box but am getting a ping error when testing the second IPIP tunnel:
bash-2.05b# ping 10.2.2.2 PING 10.2.2.2 (10.2.2.2): 56 data bytes ping: sendto: Input/output error ping: sendto: Input/output error ping: sendto: Input/output error
Did you increase net.link.gif.max_nesting via sysctl?
