# If we see IPv4 packet forwarding support in the kernel, we will turn it on.
# This was the default for 2.0.x kernels, but with recent kernels it must be
# activated through a file in /proc.  IPv4 packet forwarding support is 
# required if you plan to use your Linux machine as a router or firewall.
# If you don't want your Linux machine to forward packets, change the 1 below
# to a 0.

# When using IPv4 packet forwarding, you will also get the rp_filter, which
# automatically rejects incoming packets if the routing table entry for their
# source address doesn't match the network interface they're arriving on.  This
# has security advantages because it prevents the so-called IP spoofing,
# however it can pose problems if you use asymmetric routing (packets from you
# to a host take a different path than packets from that host to you) or if
# you operate a non-routing host which has several IP addresses on different
# interfaces.  To turn rp_filter off, uncomment the lines below:
# if [ -r /proc/sys/net/ipv4/conf/all/rp_filter ]; then
