Hi
Normally you would see a /30 (255.255.255.252) mask on a outside interface.
Instead use something that has a few more host IPs available on the
interface, i.e. /28 (255.255.255.240) which will give you 14 host IPs with
12 available after the interfaces are addressed.
I do not know if this is the recommend method from Cisco or not, but I am
using it without any problems at all.
Here is short example:
Int S0
ip add 12.168.10.1 255.255.255.240 (far side would be 12.168.10.2
255.255.255.240 leaving 3-14 available)
ip nat outside
int E0
ip add 192.168.10.1 255.255.255.0
ip nat inside
ip nat inside source list 19 interface S0 overload (this will overload the
12.168.10.1 address and allow internal users access via 1 IP)
ip nat inside source static tcp 192.168.10.6 80 12.168.10.3 80 extendable
ip nat inside source static tcp 192.168.10.7 80 12.168.10.4 80 extendable
(and so on)
ip nat inside source static tcp 192.168.10.17 80 12.168.10.14 80 extendable
ip access-list 19
permit 192.168.10.0 0.0.0.255
