Hi again Joseph! see this is the thing, it says that you need to create the lo:0, for 2 reasons #1 so that the real server knows how to get back to the VIP #2 to solve the arp problem.
for #2, I assume I use the sysctl.conf: net.ipv4.ip_forward = 1 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 on the real servers, and just ignore lo:0? if that's true, ok, but how do I solve #1 (how to show the real servers where the VIP is?) thanks!! Will... btw, I have 2.6.18 kernel... centos 5.1 On Jan 5, 2008 3:36 PM, Joseph Mack NA3T <[EMAIL PROTECTED]> wrote: > On Sat, 5 Jan 2008, William Ottley wrote: > > > I'm trying to setup a LVS-TUN, which has 3 internet connections. > > eth0 - public (client) > > eth1 - public TUN to webserver 1 > > eth2 - public TUN to webserver 2 and webserver 3 (same network) > > > > where would the VIP be? > > eth0 if you're using iproute2 tools. ethernet aliases are > deprecated (but might still work).
