Geoip redirect by country codes but exclude a client with dynamic ip

[st1905]

Hello,

The site has geoip redirection to subdomains using country codes, before
we only needed to exclude a directory from redirection but now my client
is asking me to exclude himself from it, how can I do this ? 

Please note that his ip is dynamic, thanks for any help.
