I try to create a tunnel through etherip. And I did read man pages etherip in OpenBSD. But this example aren't working in my servers.
cat /etc/sysctl.conf
net.inet.etherip.allow=1
net.inet.ip.forwarding=1
cat /etc/hostname.etherip0
tunnel 10.0.0.2 10.0.0.1
up
cat /etc/hostname.rl2
inet 10.0.0.2 255.255.255.0
cat /etc/hostname.rl0
up
cat /etc/hostname.bridge0
add rl0
add etherip0
up link2
The other side is almost the same, with a few differences. Output from tcpdump
tcpdump -i rl2 proto 97
tcpdump: listening on rl2, link-type EN10MB

16:29:20.504099 etherip 10.0.0.1 > 10.0.0.2 ver unknown len 93 [tos 0x10]
I don't see what is wrong. Why don't work etherip tunnel?
