Now we need to configure the firewall to permit incoming NFS connections.
-Edit the file /etc/sysconfig/iptables
+Create firewalldnfs.sh, and add the following content to it:
.. parsed-literal::
- -A INPUT -s 172.16.10.0/24 -m state --state NEW -p udp --dport 111 -j ACCEPT
- -A INPUT -s 172.16.10.0/24 -m state --state NEW -p tcp --dport 111 -j ACCEPT
- -A INPUT -s 172.16.10.0/24 -m state --state NEW -p tcp --dport 2049 -j
ACCEPT
- -A INPUT -s 172.16.10.0/24 -m state --state NEW -p tcp --dport 32803 -j

-Now you can restart the iptables service with the following command:
+ #!/bin/bash
+
+ firewall-cmd --direct --add-rule ipv4 filter INPUT_direct 10 -m state
--state ESTABLISHED,RELATED -j ACCEPT
Review comment:
Firewall rules may be further simplified, for example as:
```
iptables -I INPUT -p tcp -m tcp --dport 22 -j ACCEPT
iptables -I INPUT -p tcp -m tcp --dport 1798 -j ACCEPT
iptables -I INPUT -p tcp -m tcp --dport 16509 -j ACCEPT
iptables -I INPUT -p tcp -m tcp --dport 5900:6100 -j ACCEPT
iptables -I INPUT -p tcp -m tcp --dport 49152:49216 -j ACCEPT
iptables-save > /etc/sysconfig/iptables
```
Avoid firewall-cmd which I'm not if it's available by default.
