First I'll remove the previous NAT (from my last post) configuration.
router1(config)#no ip nat inside source list NAT interface Ethernet0 overload
Dynamic mapping in use, do you want to delete all entries? [no]: yes
After removing the config I verify that I cannot access the internet or ping the internet from the Win7 host.
Now I create a NAT pool with three addresses.
router1(config)#ip nat pool NAT_POOL 10.0.1.250 10.0.1.252 netmask 255.255.255.0
I already have the NAT access-list created from my previous post so I'll use that again.
router1(config)#ip nat inside source list NAT pool NAT_POOL overload
Now I access the internet from the Win7 host and verify that I am being NAT'd.
router1#sh ip nat translations
Pro Inside global Inside local Outside local Outside global
tcp 10.0.1.251:1231 10.0.2.1:1231 208.43.202.17:80 208.43.202.17:80
I can also check the NAT statistics.
