On some system we also need to install "nfs-utils-lib".

Setup Security

iptables

Normally, a specific list of ports should be provided to iptables. I tried the following, but it did not work:

...
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0 -m state --state NEW -p udp --dport 111 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0 -m state --state NEW -p tcp --dport 111 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0 -m state --state NEW -p tcp --dport 2049 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0  -m state --state NEW -p tcp --dport 32803 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0  -m state --state NEW -p udp --dport 32769 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0  -m state --state NEW -p tcp --dport 892 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0  -m state --state NEW -p udp --dport 892 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0  -m state --state NEW -p tcp --dport 875 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0  -m state --state NEW -p udp --dport 875 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0  -m state --state NEW -p tcp --dport 662 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0 -m state --state NEW -p udp --dport 662 -j ACCEPT
-A SSH -s 192.168.0.0/255.255.0.0 -j ACCEPT
...

then

service iptables restart

I ended up allowing everything from 192.168.0.0/255.255.0.0 for the duration of using the NFS.

...
-A RH-Firewall-1-INPUT -s 192.168.0.0/255.255.0.0 -j ACCEPT
