Configuring ports for a firewall
IMPORTANT:
To avoid unintended consequences, HP recommends that you configure the firewall
during scheduled maintenance times.
When configuring a firewall, you should be aware of the following:
•
SELinux should be disabled.
•
By default, NFS uses random port numbers for operations such as mounting and locking.
These ports must be fixed so that they can be listed as exceptions in a firewall configuration
file. For example, you will need to lock specific ports for
rpc.statd
,
rpc.lockd
,
rpc.mountd
, and
rpc.quotad
.
•
It is best to allow all ICMP types on all networks; however, you can limit ICMP to types 0, 3,
8, and 11 if necessary.
Be sure to open the ports listed in the following table.
