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, -- Giovanni P. Tirloni
