Cisco 7200 Series Router Question

jim · Guest

Hello,

I am trying to find the commands that would allow the WWW to route from a
static IP address
on the router's WAN port to the router's LAN port (internal lan i.e.
192.168.....) and
vice versa.

I am able to get the static IP address setup and ping the WWW, but NOT the
internal side of the router.

I am somewhat familiar with the normal commands.

The router is a 7206 with 0/1 0/2 and 0/3 GIG ports.

Any assistance is very much appreciated.

This isn't possible. 192.168.0.0/16 is not routeable across the
internet.

You need to port forward from the public address to the internal LAN.

Setup NAT, then use the following commands to port forward.

ip nat inside source static tcp 192.168.0.x [PORT NUMBER] interface
[External Interface, normally a Dialer] [External Port Number]

Let me know if you need help seting up NAT.
In summary, specifiy your internal and external interfaces, and then
setup your access lists to NAT.
i.e
ip nat inside source list internet-nat interface Dialer1 overload

with the following ACL.
ip access-list extended internet-nat
permit ip 192.168.0.0 0.0.0.255 any
