Regional IP Blocks needed for IPTABLES rules


Pardon me if my question is not directly related to Linux Security per se. I was wondering if there is a way to find out IP blocks based on a given region. I know there are IP Lookups that will tell you what Country and possibly City a given IP is from. What I want is the following:

- I would like to set up a IPTABLES rule that implements something like:

=> ALLOW VPN connections FROM THIS ISP/IP BLOCKS THAT ARE IN CITY XYZ

Basically, I want to limit my incoming VPN connections FROM my ISP in the surrounding area. So, for example, I can go to my friends house who also has the same ISP. I should be able to connect from his home to mine because we have 1) same ISP 2) IP blocks is confined to a particular local location.

Not really, you can whitelist the ip blocks of the ISP's in your area, but if they are large ISP's the IPs will be from all over.
