Long story short: I have some experience in ipsec tunnels setup. and I supposed that have configured everything properly, and to illustrate this I've loaded if_enc(4) on the 11.1 and it does show the traffic for the second gif: [skip] > Any ideas ? Always add "link2" to ifconfig_gifX configuration in such cases: ifconfig_gif0="inet 192.168.254.25 192.168.254.26 netmask 255.255.255.252 mtu 1500 link2" Refer to gif(4) manual page for details, look for IFF_LINK2 description.
