Hi Andrew, It depends on your firewall configuration on the Nagios server - but yes, the Nagios server will an outbound rule to allow traffic to destination port 5666 on your nrpe client, and also an inbound rule to allow traffic from source port 5666 on your nrpe client.
Your client will need an inbound rule allowing traffic to destination port 5666 from the Nagios server, and an outbound rule allowing traffic from source port 5666 to the Nagios server. This is good for iptables anyway, FreeBSD's ipfilter is slightly different but the principle's the same.
