Thought it could be some issue with ISP; tried the following:
Another problem, even though there is nothing connected on wan port of UC560 the LED light is flashing intermittently on the port. This is a replacement UC560 I received yesterday for a faulty UC560 I had earlier.
I have spoken to TAC, unfortunately they cannot find out why this is happening ?
I have also added the following commands
ip nat inside on VLAN 100/1/90
ip nat outside on wan port
After the above comannds now my phones are not registering either.
Any help will be appreciated.
Can you please do a "sh ip route" on the command line and post the information up here, and what would also help is a config dump to a text file with all sensitive data removed (please make sure to upload a file and not a direct post if it ).
Do you have your nat overload statement in the config?
ip nat inside source list 1 interface FastEthernet0/0 overload
access-list 1 permit 192.168.10.0 0.0.0.255
access-list 1 permit 10.1.1.0 0.0.0.255
