nginx geoip module with reverse proxy in multi tenant

[blason]

Oh Ok -

Thanks for the pointer and if my understanding is clear then define
map $geoip_country_code $allowed_country_A
map $geoip_country_code $allowed_country_B
map $geoip_country_code $allowed_country_C

under http section in /etc/nginx/nginx.conf

and then use 
if ($allowed_country_A = no) in server section?
