Hey everybody. I'm using the ip policy hack to get transparent proxy going
like this:
ip rule add prio 100 fwmark 1 table 100
ip route add local 0/0 dev lo table 100
That redirects packets that I've marked with fwmark 1 into the "local" machine
so that lvs will see them.
This is all working, I can distribute incomming connections to realservers,
however, I run into problems when I try to use the localnode feature.
If I have
/sbin/iptables -t nat -A PREROUTING -p tcp -s 10.0.0.1/8 --dport 80 -j REDIRECT
--to-port 8080
in my PREROUTING table so that the local machine can intercept, connections
routed to the local node work and connections routed to the other peers fail,
if I delete the rule connections to the local node fail and connections to the
remote hosts work.
Any ideas? Can I tell the connections apart in iptables so that I can create a
rule to skip the redirect for packets leaving for other realservers? Can I get
lvs to bypass PREROUTING for packets going out?
