So many arps from ISP on Internet CCT

[Nirbhai Gill]

I forgot the command i used to have on my cisco which would block the internet arps coming into my router and instead i would get only one arp from ISP and then I tried setting up Configuration professional and selected primary WAN interface which wiped out my WAN interface config and now I am recieving whole lots of Internet Arps on WAN. Can someone please help me disable this.?

Most likely, you have your default route wrong.  Mostly like, you are routing it via an interface rather than a specific IP address.

The only default route you should have configured is:

ip route 0.0.0.0 0.0.0.0 DHCP

Thanks for the reply..Yeah fixed it earlier in the evening..it seems like CCP changed the route too point to interface rather than ip when I selected the WAN through CCP..I never anticipated it would do that though as I thought it would have only wiped WAN config  but it added few other commands too..
