with my old linux box I forward all my LAN traffic coming from eth1 via

$IPTABLES -t nat -A POSTROUTING -o $INET_IFACE -j MASQUERADE
$IPTABLES -A FORWARD -i $LAN_IFACE -j ACCEPT
$IPTABLES -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT
Howevr I moved the box to FreeBSD 5.4 and also I have a new connection
PPPoE. I enabled the IPDIVERRT, FIRREWALL etc in the kernel but I am
unable to make traffic coming from rl0(internal interface) be forwaded
via tun0( PPPoE interface).
I have gateway_enable='yes', tried playing with ppp_nat etc...
But no luck....
Is there a simple way to do that with ipfw ? Please help - I am little
bit confused...
Actually you don't need ipfw or any other packet filter to set up a
simple internet access point for clients in a LAN. This configuration
should be enough:
---- ppp.conf ----
myisp:
set device PPPoE:<interface>
set log Phase IPCP CCP Warning Error Alert
add! default HISADDR
set authname <username>
set authkey <password>
----
Note: <interface> is your external network interface, i.e. neither rl0
nor tun0.
---- rc.conf ----
gateway_enable="YES" # "sysctl net.inet.ip.forwarding=1" at startup
ppp_enable="YES"
ppp_mode="ddial"
ppp_profile="myisp"
ppp_nat="YES" # alternatively "nat enable yes" in ppp.conf
----
I hope I didn't forget about something.
