Hi

you may try the iRule below as a starting point...

when CLIENT_ACCEPTED {
    if { [class match [IP::client_addr] equals whitelistIP] } then {
        pool insert_your_pool_name
    } else {
        switch -exact -- [whereis [IP::client_addr] country] {
            "DE" -
            "AT" -
            "CH" -
            "LI" -
            "LU" { 
                pool insert_your_pool_name
            }
            default { 
                reject
            }
        }
    }
}

Note: Reordered the 

[if]
and 
[switch]
nestings, optimized the 
[switch]
command and finally changed the 
[matchclass]
(is a deprecated command) to become 
[class match]
.

Cheers, Kai
