The configuration:
ip nat inside source list 12 interface Ethernet1 overload
ip nat inside source static tcp 192.168.100.7 80 203.144.156.67 80 extendable
ip nat inside source static tcp 192.168.100.7 203.144.156.68
In this configuration internet clients are able to browse to 203.144.156.67 . But 203.144.156.68 does not work. But when I removed the extendable line 203.144.156.67, internet clients are able to browse to 203.144.156.68 .
Why can't both external ip 203.144.156.67 & 203.144.156.68 coexists and work at the same time??? But if one is down the other will work fine..
