Question TCP/UDP port range for default AIX NFS?

May I know what is the TCP/UCP port range for any default AIX NFS? Based on rpcinfo -p, I got the following output:

program vers proto port service
100000 4 udp 111 portmapper
100000 3 udp 111 portmapper
100000 2 udp 111 portmapper
100000 4 tcp 111 portmapper
100000 3 tcp 111 portmapper
100000 2 tcp 111 portmapper
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs
100003 4 tcp 2049 nfs
200006 1 udp 2049
200006 4 udp 2049
200006 1 tcp 2049
200006 4 tcp 2049
100005 1 tcp 32769 mountd
100005 2 tcp 32769 mountd
100005 3 tcp 32769 mountd
100005 1 udp 32793 mountd
100005 2 udp 32793 mountd
100005 3 udp 32793 mountd
400005 1 udp 32794
100024 1 tcp 32770 status
100024 1 udp 32795 status
100133 1 tcp 32770
100133 1 udp 32795
200001 1 tcp 32770
200001 1 udp 32795
200001 2 tcp 32770
200001 2 udp 32795
100021 1 udp 32820 nlockmgr
100021 2 udp 32820 nlockmgr
100021 3 udp 32820 nlockmgr
100021 4 udp 32820 nlockmgr
100021 1 tcp 32771 nlockmgr
100021 2 tcp 32771 nlockmgr
100021 3 tcp 32771 nlockmgr
100021 4 tcp 32771 nlockmgr
200012 2 udp 702
200012 3 udp 703

I didn't see any NFS port range in /etc/environment. In order to setup NFS behind a firewall, what are the ports/port range we should open?

Thanks.
