I use the netmask 255.255.255.240 on my Class C, in order to have subnets of 14 hosts each. Since I want to devote one subnet to the PPP clients, and applying the rule (from the doc.) that PPP server and clients must be on the same subnet, I started to define an IP alias for my FreeBSD's ed0 [193.72.189.2], following the doc's suggestions. That is: ifconfig ed0 inet 193.72.189.17 netmask 255.255.255.240 alias route add -host 183.72.189.17 127.0.0.1 0 Everything seems to be working fine for a while, but then the FreeBSD "looses" the route to the Cisco, since it expires. Question: What am I doing wrong? You're using static routes, yet you probably didn't turn off routed in the FreeBSD box. If you run netstat -r on the FreeBSD box, is the default route missing? And can you re-add it using 'route add default <IP_ADDR>', and then it disappears after a while again? If so, routed running is probably your problem. -- Deborah Gronke Bennett System Software Engineer, IOS Technology deborah@cisco.com (408)-526-4000 Cisco Systems 170 West Tasman Dr., San Jose, CA 95134-1706
