Hi Sameer,
I have resolved this problem, actually the problem is with my
arno-iptablefirewall, i shut down the firewall at Real servers and
configured the Real servers again for tunuling and ARP ignore/announce, it
worked fine, i run this test several times.
BUT THE real BIG problem is, i can not shutdown the arno-iptables-firewall
on production machines. I guess, as i am doing tunling which is ipip
incapsulation, firewall is rejecting those IP packates. May be they are
filtered by spoofing filter. thats why nothing on tcpdum at port 443.
Do you know how to modify this rule in iptable.
Regards
Anil Sharma
