You don't the routing at bootup, but when the ppp link comes up. And you can achieve what you want by hacking into /etc/ppp/ip-up.local (see the pppd man page and /etc/ppp/ip-up). Forwarding is turned up at bootup by changing this line in /etc/sysctl.conf to be 1 and not 0... net.ipv4.ip_forward = 1 Then run /sbin/sysctl to enable it right away. (It will then be automatically done each bootup). The relevant nat modules can be loaded with the ip_tables module by adding something like this to /etc/modules.conf... alias ipfwadm off alias ipchains off add above ip_tables iptable_filter iptable_mangle iptable_nat ip_conntrack ipt_state ipt_unclean ipt_LOG ipt_limit add above ip_conntrack ip_conntrack_ftp ip_conntrack_irc add above iptable_nat ipt_MASQUERADE ip_nat_ftp This might be overkill for your particular situation, so you'll probably need to play around with it to get what you want. BTW, all sorts of magic like this can be done in /etc/modules.conf, the "add above" and "add below" are just two of the many spells that can be cast in there. The "post-install" and "pre-removal" directives are also very useful. > David Willson > xMCT, MCSE, Network+, A+, Linux Enthusiast > http://TheGeek.NU Hope this helps to point you in the right direction.
