Let's look for wierd reasons. o make sure there are no iptables rules on any of the machines. o test with local client (not through proxy) connecting to VIP o make sure there is no physical route from the realserver to the client except throught the DIP - ie no routes that an imcp redirect that change. check your routes with ip route show (not `route -n`) o test with a simple client. telnet is best (to port 23) then next best is telnet to port 80 and do a GET Joe -- Joseph Mack NA3T EME(B,D), FM05lw North Carolina jmack (at) wm7d (dot) net - azimuthal equidistant map generator at http://www.wm7d.net/azproj.shtml Homepage http://www.austintek.com/ It's GNU/Linux! _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - [email protected] Send requests to [email protected] or go to http://lists.graemef.net/mailman/listinfo/lvs-users
