I have a redhat 9.0 server and it is its own dns server for <a href="http://www.ourowndomain.com" rel="ugc">www.ourowndomain.com</a>&nbsp;and other two virtual domains.<br />
<br />
I have configured firewall for ssh, telnet, pop, and all that stuff but when i start iptables i can´t get mail for user@virtualdomain.com but it works for user@maindomain.com, so i think the problem is anything related with DNS (i use named)<br />
<br />
What port do i have to enable in iptables in order to other external servers can send mail to my_virtual_domain ?<br />

IPTABLES &amp; named (dns)

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
