	I have tried:

legendre# ifconfig tap0
tap0: flags=0x8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
        ec_capabilities=0x5<VLAN_MTU,JUMBO_MTU>
        ec_enabled=0
        address: f2:0b:a4:38:bb:42
        status: no carrier
        inet6 2001:7a8:a8ed:1::2/64 flags 0x8<DETACHED>
        inet6 fe80::f00b:a4ff:fe38:bb42%tap0/64 flags 0x8<DETACHED>
scopeid 0x9
        inet 192.168.1.2/24 broadcast 192.168.1.255 flags 0x4<DETACHED>

legendre# ping -I 192.168.1.2 192.168.1.1
PING rayleigh.systella.fr (192.168.1.1): 56 data bytes
^C
----rayleigh.systella.fr PING Statistics----
52 packets transmitted, 0 packets received, 100.0% packet loss
legendre#

	Other constatation : openvpn server cannot ping openvpn client (netbsd)
but can ping workstations on lan1 through VPN.

	Best regards,
