I am trying to set up a linux router and am wondering if there is a way to use the kernel routing table (ie. route command) instead of setting up the NAT table in iptables when forwarding packets from external machines.
Distribution: Slackware, CentOS. Red Hat Enterprise Linux

Rep:
You can only do this if all your clients have routable IP addresses (i.e. not 192.168.X.X), which is a) unlikely and b) very, very insecure. The kernel routing table only handles routing packets, not rewriting the packet headers to do address translation. You will need to use NAT.
