Friends,
Mind the following scenario,
There is an internal server, which is being masked under a router's
interface.
ROUTER---Ethernet0/0-(192.168.1.1)-----------EXTERIOR WORLD
|
|
INTERNAL WORLD
The question: When is the "extendable" keyword required?
1- Allways? (meaning in any of the two following variants of the
command)
ip nat inside source static tcp 173.2.5.100 443 interface
Ethernet0/0 443 extendable
ip nat inside source static tcp 173.2.5.100 110 interface
Ethernet0/0 110 extendable
ip nat inside source static tcp 173.2.5.100 80 interface
Ethernet0/0 80 extendable
ip nat inside source static tcp 173.2.5.100 25 interface
Ethernet0/0 25 extendable
or
ip nat inside source static tcp 173.2.5.100 443 interface
192.168.1.1 443 extendable
ip nat inside source static tcp 173.2.5.100 110 interface
192.168.1.1 110 extendable
ip nat inside source static tcp 173.2.5.100 80 interface
192.168.1.1 80 extendable
ip nat inside source static tcp 173.2.5.100 25 interface
192.168.1.1 25 extendable
2- Just when the Inside Global is entered as an instead of the interface
name?
ip nat inside source static tcp 173.2.5.100 443 interface 192.168.1.5
443 extendable
ip nat inside source static tcp 173.2.5.100 110 interface 192.168.1.5
110 extendable
ip nat inside source static tcp 173.2.5.100 80 interface 192.168.1.5 80
extendable
ip nat inside source static tcp 173.2.5.100 25 interface 192.168.1.5 25
extendable
Best Regards,
Roberto
