Hi all,
I'm stuck with an issue with my home lab.
Here are the scenario:
Have a router (cisco 1841) connected with a Modem (ISP). The modem from the provider doesn't allow me to create a static route so i'm using NAT. The router is acting as a DHCP server of my LAN.
My router have two interfaces configured:
Fa0/0 - LAN
ip address 192.168.0.1 255.255.255.0
speed 100
duplex full
ip nat inside
no shutdown
Fa0/0/0 - INTERNET (TRANSIT SEGMENT)
ip address 10.0.0.2 255.255.255.0
speed 100
duplex full
ip nat outside
no shutdown
On the modem i have the ip 10.0.0.1
So here is the strange thing:
From the router i can ping google.com(DNS and IP) using both interfaces as Source. I also ping 10.0.0.1 fine. NAT translations for this communication (FROM THE ROUTER) works fine.
I have a computer connected direct on FA0/0. From this computer i can ping 192.168.0.1 and 10.0.0.2. But i can't ping www.google.com(DNS and IP)or 10.0.0.1.
No NAT Translations are created.
BUTTTTTTTTTTTT
Sometimes this communication works but most of the time it not work properly. I had upgrade the IOS but the issue remains.
Need help with that.
