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

100021 2 udp 32820 nlockmgr

100021 1 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.

rpcinfo
RPCINFO(8) BSD System Manager's Manual RPCINFO(8)
NAME
rpcinfo -- report RPC information
SYNOPSIS
rpcinfo -p [host]
rpcinfo [-n portnum] -u host program [version]
rpcinfo [-n portnum] -t host program [version]
rpcinfo -b program version
rpcinfo -d program version
DESCRIPTION
rpcinfo makes an RPC call to an RPC server and reports what it finds.
OPTIONS
-p Probe the portmapper on host, and print a list of all registered RPC programs. If host is not specified, it defaults to the value
returned by hostname(1).
-u Make an RPC call to procedure 0 of program on the specified host using UDP, and report whether a response was received.
-t Make an RPC call to procedure 0 of program on the specified host using TCP, and report whether a response was received.
-n Use portnum as the port number for the -t and -u options instead of the port number given by the portmapper.
-b Make an RPC broadcast to procedure 0 of the specified program and version using UDP and report all hosts that respond.
-d Delete registration for the RPC service of the specified program and version. This option can be exercised only by the super-user.
The program argument can be either a name or a number.
If a version is specified, rpcinfo attempts to call that version of the specified program. Otherwise, rpcinfo attempts to find all the reg-
istered version numbers for the specified program by calling version 0 (which is presumed not to exist; if it does exist, rpcinfo attempts to
obtain this information by calling an extremely high version number instead) and attempts to call each registered version. Note: the version
number is required for -b and -d options.
EXAMPLES
To show all of the RPC services registered on the local machine use:
example% rpcinfo -p
To show all of the RPC services registered on the machine named klaxon use:
example% rpcinfo -p klaxon
To show all machines on the local net that are running the Yellow Pages service use:
example% rpcinfo -b ypserv 'version' | uniq
where 'version' is the current Yellow Pages version obtained from the results of the -p switch above.
To delete the registration for version 1 of the walld service use:
example% rpcinfo -d walld 1

BUGS
In releases prior to SunOS 3.0, the Network File System (NFS) did not register itself with the portmapper; rpcinfo cannot be used to make RPC
calls to the NFS server on hosts running such releases.
