My bad. Else condition is rejecting all traffic. Try below and I would suggest try on non-prod VIP first.

 

when HTTP_REQUEST { 
    set ip_reputation_categories [IP::reputation [IP::client_addr]]
    if {([$ip_reputation_categories contains "Spam Sources"]) and (!([[whereis [IP::client_addr] country] equals "NP"]))} {
	log local0. "IP from spam sources block: [IP::client_addr]"
	drop
	} else {
	#DO NOTHING
	}
  }

Few lines were also added for the debugging purpose in the provided iRule as discussed before.

when HTTP_REQUEST { 
    set ip_reputation_categories [IP::reputation [IP::client_addr]]
    if {([$ip_reputation_categories contains "Spam Sources"]) and (!([[whereis [IP::client_addr] country] equals "NP"]))} {
    log local0. "IP from spam sources block: [IP::client_addr]"
    drop
    } else {
    log local0. "IP from spam sources from Nepal, allow: [IP::client_addr]"
    #DO NOTHING
    }
  }



However after few minutes of attaching the iRule on the virtual server, the application stopped working. 

While the following error logs were found on the /var/log/ltm,

It seems the iRule is still not valid to check the IPI category variable especially for the 

[$ip_reputation_categories contains "Spam Sources"]
