I have 32 Static IP address and i want to NAT 7 IP address to access internet internally.the intenal ip range is 172.26.x.x.i like to know how to config this in 2800 router
if you want internet access from your 172.16.x.x LAN then you can do NAT overload
1) you create an ACL telling your router which IP addresses must be natted
access-list 10 permit 172.16.x.x 0.0.0.255 (this is the wildcard mask if you have a /24 subnet)
2) select inside and outside interfaces with the nat inside and nat outside commands on right interface
3) configure nat overload: ip nat inside source list 10 interface XX where XX is the id of outside interface.
Hope this is clear enough.
To verify just do a ping from one machine in the LAN to an internet address and then : show ip nat translation ---> you should see an entry for your ping
