IPsec isakmp_natt problem on racoon.conf

I have this weird problem where racoon complains of the following error:

WARNING: NAT-T is enabled in at least one remote{} section, but no 'isakmp_natt' address was specified!

I've already specified isakmp_natt though. Here's my racoon.conf:

path pre_shared_key "/var/etc/psk.txt";

path certificate  "/var/etc";

listen
{
    isakmp 172.17.69.69 [500];
    isakmp_natt 172.17.69.69 [4500];
}
