Hi,
I have two mirrored clones of CentOS 6.2 with l2tpv3tun in a lab/test
environment.
With each I set some variables...
export tunid=1
export peerid=1
export sport=5000
export dport=5001
export localip=21.21.21.2
export remoteip=20.20.20.2
export l2iplocal=10.5.1.2
export l2ipremote=10.5.1.1
And the reverse on the other box:
export tunid=2
export peerid=2
export sport=5001
export dport=5000
export localip=20.20.20.2
export remoteip=21.21.21.2
export l2iplocal=10.5.1.1
export l2ipremote=10.5.1.2
Then I run:
l2tpv3tun add tunnel tunnel_id $tunid peer_tunnel_id $peerid
udp_sport $sport udp_dport $dport encap udp local $localip remote
$remoteip
l2tpv3tun add session tunnel_id $tunid session_id $tunid peer_session_id $tunid
ip addr add ${l2iplocal}/32 peer ${l2ipremote}/32 dev l2tpeth0
ifconfig l2tpeth0 up
I see the new device:
l2tpeth0 Link encap:Ethernet HWaddr 5E:E3:5F:0F:83:95
inet addr:10.5.1.1 Bcast:0.0.0.0 Mask:255.255.255.255

[root@box20 ~]# l2tpv3tun show tunnel
Tunnel 2, encap UDP
From 20.20.20.2 to 21.21.21.2
Peer tunnel 2
UDP source / dest ports: 5001/5000
[root@box20 ~]# l2tpv3tun show session
Session 2 in tunnel 2
Peer session 2, tunnel 2
interface name: l2tpeth0
offset 0, peer offset 0
pings to the eth0 IPs (20.20.20.2/21.21.21.2) work, but no luck on the
l2tpeth0 device's IPs (10.5.1.1/10.5.1.2). OpenSwan is installed and
bound to eth0 (using netkey). Even with openswan / ipsec service off,
no pings.
If anyone can offer some guidance I would appreciate it. :-)
