I've successfully patched and rebuilt Horms' RedHat 9 Ultramonkey kernel
(kernel-2.4.20-24.9.um.1.src.rpm) with the 2.4.23 NFCT patch. I've also
enabled connection tracking and SNAT reroute runtime support. I'm trying to
figure out how to get DNAT to work. In a simple NAT LVS setup with 2
realservers, the realservers (running both Apache and a JAVA app server) must
occationally make a HTTP request to a VIP living on the director.
I currently have an IPTABLES rule that makes each server view the VIP as local,
but if the Apache server goes down, I have no failover. How can I have
requests sent to the director's VIP redirected back into the cluster and the
same network?
Assuming this would require a DNAT-type setup, I've added the following
IPTABLES rule on the the director, with no success. 192.168.0.40 is the VIP.
The realservers live on 10.0.5.0/24.
-A POSTROUTING -s 10.0.5.0/255.255.255.0 -d 192.168.0.40 -p tcp -m tcp --dport
80 -j SNAT --to-source 10.0.5.1
