I'm trying to test gre(4) tunnel.
Both machines in one LAN. OpenBSD has IP 192.50.51.52, another end -
192.50.51.28.
# ifconfig gre0
gre0: flags=9011UP,POINTOPOINT,LINK0,MULTICAST mtu 1476
groups: gre
physical address inet 192.50.51.52 -- 192.50.51.28
inet6
Salut,

Did you set net.inet.gre.allow to 1?
Yes.
# sysctl net.inet.gre
net.inet.gre.allow=1
net.inet.gre.wccp=0

First of all, use an empirical methodology.
Destroy your gre tunnel with
ifconfig gre0 down
ifconfig gre0 destroy
Clear

Done.
Clear your ARP table.
arp -ad
Done.
Try to reach 192.50.51.28. For example with ping or telnet to port 22.
Then check arp table entry
