Hi and thanks for your reply. I've followed your advice and I've tested telnet with LVS-DR. On the real servers I configured lo:110 and added the following in /etc/sysctl.conf:
net.ipv4.conf.lo.arp_ignore = 1 net.ipv4.conf.lo.arp_announce = 2 net.ipv4.conf.all.arp_ignore = 1 net.ipv4.conf.all.arp_announce = 2 None of the real servers ARP's which is good and everything worked perfectly. I took the same servers, removed lo and configured tunl0:110 to test LVS-TUN. When I telnet from a linux machine I get the same real server. The VIP address in the arp table is unfortunately the same as one of the real servers. When I try a telnet connection from a windows machine I only get a timeout: Connecting To 172.24.30.110...Could not open connection to the host, on port 23: Connect failed Isn't it sufficient to add the lines in /etc/sysctl.conf or do I have to patch the kernel (I run 2.6.22 btw)?
