I'm still trying to wrap my mind around subnetting and was hoping somebody here could point me in the right direction. I am setting up a mail server and hardware firewall (Sonicwall) behind a DSL router. The ISP has given me a &quot;/29&quot; subnet which should have 6 usable IP addresses. They gave me the following information about these IP's (I've hidden the first 3 blocks for privacy):<br />
x.x.x.32 = Subnet<br />
x.x.x.33-39 = Usable IP's<br />
x.x.x.40 = Broadcast<br />
<br />
I want the firewall to have it's own WAN IP (.33 perhaps?) that is seperate from the DSL router's WAN IP.<br />
<br />
I have another site that is already configured with this setup and was planning on copying their configuration but I wanted to understand exactly what I'm doing. At this other site, they have the DSL router's WAN subnet mask set to 255.255.255.248 and the LAN subnet mask set to 255.255.255.252. They also have the WAN subnet mask on the firewall set to 255.255.255.248 with it's own WAN IP. Can anybody explain how all of this works or point me to a good link? Thanks!

How do you setup a firewall on it's own IP using a /29 subnet?

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).
