I have 2 PCs: one configured as gateway (PC1) and the other one (PC2) configured to use PC1 as gateway. PC1 runs LFS. It has ip
forwarding enabled (e.g. by echo 'net.ipv4.ip_forward = 1' >> /etc/sysctl.conf).
As far as I understand, I do not need to do anything else to make the kernel
route traffic to and from PC2, right?
However, if I have one PC more - PC3, and I do not wnat to route traffic to and
from it I need to configure the kernel, e.g. with
the help of iptables. Now if I do so, i.e. use iptables to configure the
kernel, save the iptables configuration, setup the system
to reload it at startup (using the init.d scripts), is there any moment (during
system startup) when ip forwarding has been enabled
but the iptables configuration has not yet been loaded and traffic could be
routed to and from PC3?
