I have a question about NAT overload (PAT). I have used the configuration
below where 100.100.14.129 is the outside address of the router and
192.168.1.1 is the internet E0. The pool is set up for only a single address
(100.100.14.131) using overload. But when it is used, the first workstation
connects and fills the pool up to 100% and no other user can get out! See
'sh ip nat stat' below. The 'sh ip nat trans' only shows the static
translations.
Then, I can go in, remove the access-list, remove the 2 nat pool statements,
clear that NAT translations and then put the pool statements and access-list
back in just like it was (copy and paste) and it will start working.
What am I doing wrong?
ip nat pool ABC 100.100.14.131 100.100.14.131 netmask 255.255.255.192
ip nat inside source list 1 pool ABC overload
ip nat inside source static 192.168.1.1 100.100.14.129
!
