Cisco 1941 Serial interface(G703) setup but we cant ping WAN IP?
We have set the router up as per the ISP's requirements, both serial interface (E1/T1 G703) & protocol are up & we've entered the required WAN ip & subnet etc but we are unable to ping it directly from itself or from outside, any help would be greatly appreciated.

Hi, no we cant ping the ISP or any other WAN address. I think it may be due to no specific entries on the ACL? I am trying to add 'permit' to access list 23 (already existed) but cannot add anything to it? When I add the line from 'configure terminal' 'access-list 23 permit tcp any any' its seems to run the command then shows an error 'invalid input detected' & the pointer (^) is on one of the dns entries?
