Re: cisco 877

In order to do nat for the inside users, do the following:

//this is the access list that will permit the required subnets or hosts for natting

ip access-list extended NAT

permit ip 192.168.x.x 0.0.255.255

// this is the route map that match the access list mentioned above

route-map nat-map permit 1

match ip address NAT

//this is the natting command that contains the route map, source, and also the outside interface which is dialer 0 for Cisco877, overload means all the inside users(192.168.x.x) will have one IP address which is 83.x.x.x (since this is static IP)

ip nat inside source route-map nat-map interface Dialer0 overload

// this is will be applied at the inside interface "gateway" for the inside interface. "if the vlan & wireless interfaces are bridged, then this is applied at the BVI interface"

ip nat inside

//this is applied at the outside interface, dialer 0 interface

ip nat outside

I hope this is helpful
