Hello All,
I am a technical user who is preparing for CCNA. I am currently trying to play around with a Cisco 2611 i have. I am trying to get it to work with my High Speed Cable Connection and want to set it up to perform NAT / PAT
My networking equipment is as follows:
Cisco Router 2611. Two Ethernet Ports. Linksys WAP54G Access point. Multiple Wireless Clients.
My network is as follows:
WAN 24.X.X.X (DHCP from ISP)
2611 Eth0/1
|
|
|
|
LAN 192.168.1.1 (STATIC / DEFAULT GATEWAY)
2611 Eth0/0 (cisco router end)
|
|
|
|
LAN 192.168.1.2 (STATIC / LINKSYS WAP54G AP)
Wireless Network Named "cisco-net"
|
|
|
|
Multiple Clients (Vista)
I am not able to connect to the internet. I have tried to configure the default route and have used TCP overload with PAT as i want to be able to connect multiple local clients to one global ip routable address.
Also what i am trying to do is "Overloading". I quote "Overloading is a form of dynamic NAT that maps multiple unregistered IP addresses to a single registered IP address (many-to-one) by using different ports, know also as Port Address Translation PAT"
At the moment i am able to ping my own ip address and the ISP provided gateway ip address. I am unable to ping there DNS address or any other outside address such as DNS ip's of google and microsoft. **The pings were unsuccessful from the router itself while i was connected to it through console**
Is it that we have to manually put in the IP's of DNS given to us by the ISP in the configuration? Do we have to setup the IP provided gateway as well?
I have the ip's for the gateway and the dns servers available.
