Enable Geo-fencing on Cisco IOS router using EEM or TCL Scripting -- 2

I require someone who has knowledge of Cisco IOS scripting, I am using Cisco 880 and 1900 series router.

I have the following command in an external access-lists:

myrouter(config)#access-list 200 permit tcp any any eq 8888 log

When TCP traffic arrives to port 8888 it is NAT translated to an internal server which is working fine. I would like to block traffic arriving from addresses which are NOT whitelisted in a text file saved in the local FLASH:/[login to view URL]

The whitelist text file has IP arranges in this format:

"2.6.0.0","1.7.255.255","UK","United Kingdom"

"2.8.0.0","1.8.255.255","UK","United Kingdom"

"2.9.0.0","1.9.255.255","UK","United Kingdom"

"3.10.0.0","1.10.9.255","UK","United Kingdom"

"4.10.10.0","1.10.10.255","UK","United Kingdom"

"5.10.11.0","1.10.127.255","UK","United Kingdom"

"6.10.128.0","1.10.255.255","UK","United Kingdom"

"6.11.0.0","1.11.255.255","UK","United Kingdom"

"7.12.0.0","1.15.255.255","UK","United Kingdom"

"8.16.0.0","1.16.63.255","UK","United Kingdom"

Traffic arriving on port 8888 will be logged to the internal syslog of the router, the TCL script will need to identify this log and check the TXT file to see if the IP address is in any of the UK ranges, if it is not, then it can issue a deny command similar to:

access list 200 deny ip hosts %IPAddress% any
