Allow Us Based Ip To Crawl Website….

Hello from a snowy London!

Basically for legal reasons a disclaimer has to be placed on every page of my website - the website is based in Hungary and therefore every person who searches for the website must see this disclaimer, however only if they are searching from Hungary. Do you think the best method would be to setup an IP filter that would allow Googlebot to crawl the website or do you think there is a more suitable method?

If anyone has any tips on setting up this type of filter then please let me know!
