Ok, I've tried this and it doesn't quite seem to work. Now the route on the
cisco is not pointing at that machine, but my client machine
(207.228.64.120) has explicit routes for the 2 1/2 Class C's listed in the
ipchains commands below, routed to (207.228.64.64), which is my linux
director. Doing traceroutes shows the packets hit the director and get
forwarded to the router. Now I've made sure that I have all the right stuff
compiled into my kernel, the module for marked packets is called
ip_masq_mfw.o (as opposed to what the help says in the make menuconfig,
ip_masq_markfw.o). But that modules isn't loaded at startup, and even if I
insmod it it doesn't make a difference.. So have I missed something real
small somewhere along the way?
This is my config file so far:
#setup
echo "1" > /proc/sys/net/ipv4/ip_forward
ipchains -F
ipvsadm -C
#firewall packet marking
ipchains -A input -s 0.0.0.0/0 -d 207.228.79.0/25 -m 1
ipchains -A input -s 0.0.0.0/0 -d 207.148.155.0/24 -m 1
ipchains -A input -s 0.0.0.0/0 -d 207.148.151.0/24 -m 1
