[c-nsp] GRE tunnel to FreeBSD

[Tuc at T-B-O-H.NET]

Hi,

	Wondering if anyone had experience with a GRE tunnel to a 
FreeBSD server. 

I've set it up on 2 devices on the same subnet. Would this be a problem from
the start? I have my FreeBSD at 192.168.3.21 and gre0 looks like :

gre0: flags=9051<UP,POINTOPOINT,RUNNING,LINK0,MULTICAST> mtu 1476
        tunnel inet 192.168.3.21 --> 192.168.3.149
        inet6 fe80::212:3fff:fedd:58b2%gre0 prefixlen 64 scopeid 0x7 
        inet 192.168.3.21 --> 192.168.3.149 netmask 0xffffffff 

        My Cisco is at 192.168.3.149 and looks like :

interface Tunnel0
 ip unnumbered Ethernet0
 tunnel source Ethernet0
 tunnel destination 192.168.3.21
!
interface Ethernet0
 ip address 192.168.3.149 255.255.255.0


        When I try to ping the Cisco after I bring the gre0 up, I
can't. To talk to the device again I have to down the tunnel.

        Ideas?

                Thanks, Tuc
