tun interface address conflict

[Giovanni P. Tirloni]

Hi,

  I tried to connect two ADSL lines from the same telco using ppp but 
it breaks when setting the second interface. The problem seems an 
address conflict between them, like this:

# ifconfig tun1 192.168.100.1 192.168.100.254 netmask 255.255.255.255
# ifconfig tun2 192.168.100.2 192.168.100.254 netmask 255.255.255.255
ifconfig: ioctl (SIOCAIFADDR): File exists

  "File exists" is the same error that I find on /var/log/ppp.log. Is 
there anything that can be done to use both at the same time?

Thanks,
