i recently added a Cisco 5510 Firewall in front of my server to block several countries from accessing my site.
Since I am not a pro I was wondering how to do that?!
I have started the ASDM manager and I am able to add rules (as far as I understand).
Now I can take from here:
IP Ranges from certain countries, e.g. China.
Question: how to import this whole list of IP Ranges into the firewall to block the outside requests from those without adding every range manually?!
I tried to figure this out but no luck, there must me away though.
Any hints or step-by-step guides are appreciated!
