default-route in the network

[Amit Singh2000]

Hello genius minds.

I have a network of about 50 sites connected via MPLs. We have a default- route in the network for Internet access. The company has decided to remove this default route and use proxy for Internet access for security purposes.

Now before we remove that. We would like to see what application or who ( source ip) is using this default route. So that we can try to see dependencies. How can I achieve this ?

Any ideas.

Thanks in advance

Hello Amit,

There are few ways that i can think as of now is to enable,

1) Sniffer/Packet capture/Span session

2) Enabling IP accounting

Thanks,

Richard.

Hi Amit

The router which is originating default route must also participate in NATing also. The best is to check the NAT logs and you will come to know which source IPs are using which applications in the basics of ports.
