Hi List.
My ISP set up this "IPVPN":
A location:
VLAN4093: ww.xx.yy.zz/30
Public IP to Internet.
VLAN4094: 192.168.0.2/30
Endpoint of "VPN" (a tunnel to B)
B location:
192.168.1.2/30 (No VLAN)
I thought that I can set up an point-to-point connection. But this is
only available for PPP/SLIP/etc. "driven" interfaces.
I can set up the connection with the following lines in my interfaces file:
auto vlan4094
iface vlan4094 inet static
address 192.168.0.2
netmask 255.255.255.255
pointopoint 192.168.1.2
vlan_raw_device wan3
up /sbin/ifconfig vlan4094 up arp
up /sbin/route add -host 192.168.1.2 dev vlan4094
down /sbin/route del -host 192.168.1.2 dev vlan4094
This works, however the interface just ignores the pointopoint line....
My question is maybe offtopic, but anyone knows a good reason why the
pointopoint feature is not available on "normal" interfaces?
Thanx,
Swifty

So what's the output of `ip addr`?

Tricky :)
