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.?
Example
Internet 192.168.20.6 10 00d9.xxxx.xxxx ARPA Vlan20
Internet 192.168.30.1 - 2c54.xxxx.xxxx ARPA Vlan30
Internet 198.41.214.67 21 0023.xxxx.xxxx ARPA GigabitEthernet1 <<<<INTERNET WAN Interface
Internet 198.41.214.68 15 0023.xxxx.xxxx ARPA GigabitEthernet1
Internet 198.252.206.25 15 0023.xxxx.xxxx ARPA GigabitEthernet1

Internet 207.102.177.22 28 0023.xxxx.xxxx ARPA GigabitEthernet1
Internet 207.102.177.120 29 0023.xxxx.xxxx ARPA GigabitEthernet1
Internet 207.102.185.216 29 0023.xxxx.xxxx ARPA GigabitEthernet1

Internet 207.228.125.115 15 0023.xxxx.xxxx ARPA GigabitEthernet1
before this there was only one arp from Gi1.

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..
