NAT

On Cisco Router 3640.

E0/0 - 192.168.2.x

IP NAT INSIDE

S0/0 - 164.164.76.x

IP NAT OUTSIDE

ip nat pool first 164.164.76.121 164.164.76.126 255.255.255.224

ip nat inside source list 1 pool first overload

access-list 1 permit ip 192.168.2.0 0.0.0.255

ip nat inside source static 192.168.2.10 164.164.76.10

---------------------------------------------------------------------------------------------------------

When i do this config on my router I am not able to ping 164.164.76.10 from any outside device and i am not able browse this web server.

If I remove NAT OUTSIDE on serial I am able to ping this IP from any outside device, but I am not able to browse this web server.

I need the following:

1) My aim is to browse this web server from any outside device using NAT

2) Any public IP address assigned to internal host should be masked to any of the NAT POOL public ip address defined on the router

Thanks,

Sridhar

Re: NAT

Try to use the following command to forward port 80 over your NAT-router:

ip nat inside source static tcp 192.168.2.10 80 164.164.76.x 80 extendable

This should work under all circumstances. Then try what happen when you replace x by the figure 10.

Goodluck,

Leo

Re: NAT

One other suggestion:

It may help a lot when you exempt IP adress 192.168.2.10 from NAT by changing access-list 1:

access-list 1 deny ip 192.168.2.10 0.0.0.0

access-list 1 permit ip 192.168.2.0 0.0.0.255
