It's not working for bridge mode.!! on ESX3.5
If u config wan interface on VSwitch0 and Lan interface on VSwitch1 and Wan in 'Vmnetwork1' ,Wan in 'Vmnetwork2'.
So if u config to used bridge mode lan as wan and try to ping to any ip from host behind lan interface it's can't ping out.
But If try config to NAT mode it work on same structure.
If Anybody can simmulate and work fine on network structure above.Let me know.
