Is this a lab setup? Does the x.x.x.73 device have a route back to 10.0.2.0? If simulating a connection to an ISP you would normally NAT this traffic so that 10.0.2.0 traffic going out the WAN interface gets translated to the public IP x.x.x.76.

Is this a router or a Layer 3 Switch?

[Mark Malone · Accepted solution]

Yes your missing NAT agree with that

800 series are routers , with switch modules

Thanks

Thanks for your reply Brandon, it is lab setup but i have no control over .73 device as it is ISP owned

I will give it a go!

Kind regards
