In Lenny, "man openvpn" states,
"First, ensure that IP forwarding is enabled on both peers. On Linux,
enable routing:
echo 1 > /proc/sys/net/ipv4/ip_forward"
That is an interactive approach whereas in /etc/sysctl.conf I set
net.ipv4.ip_forward=1
.
"man openvpn" continues,
"... enable TUN packet forwarding through the firewall:
iptables -A FORWARD -i tun+ -j ACCEPT"
>From this I infer that permission for TUN packet forwarding
is distinct from general packet forwarding. Correct?
What would be the conventional way to turn this on
permanently in Lenny?
