I want to setup a FreeBSD machine to the Internet via PPPoE and DSL.
This is no problem with the basic installation. But if I want to run it
with natd and a firewall it does not work. To connect to the ISP is no
problem, but I can not send and do not receive any data.
My /etc/rc.conf has following entries:
ifconfig ed0 up # start PPPoE-interface
gateway_enable="YES"
firewall_enable="YES"
firewall_script="name of firewall script"
ppp_nat="NO"
natd_enable="YES"
natd_interface="tun0"
natd_flags="-dynamic"
As proposed in manpage natd(8) I have following firewall script:
/sbin/ipfw -f flush
/sbin/ipfw add 50 divert natd all from any to any via tun0
/sbin/ipfw add pass all from any to any
At boot time I get these messages:
ipfw : warning: interface " tun0 " does not exist (at
proceeding the firewall script)
Firewall rules loaded, starting divert daemons: natdnatd :
Unknown interface name tun0
Can anybody tell what's wrong here?
Thanks
Klaus
