Even if it is going to use VLAN 65 it still needs an address. The older models do not support VLAN tagging. Look at an XTM 25 or maybe an XTM 33. They have similar specs to the 750 and are not prohibitively expensive for most.

the docs show that the box will support VLAN's on trusted and optional interfaces, but not on the external interface. &nbsp;An intermediary switch was the best solution.

Were you able to get the switch solution to work? &nbsp;Just curious.

We recently had to change our ISP router to use VLANs in order to split our public address space into 2 subnets. &nbsp;Now I need to reconfigure the firewall (watchguard x750e) to use the VLAN (65) instead of the external address. &nbsp;I know the firewall has VLAN capabilities, but I do not know how to configure it. &nbsp;Any help or pointers would be most welcome.<br />
<br />
original config &nbsp;(ip #'s changed to protect the innocent):<br />
ISP 1.2.3.4 &nbsp; firewall interface (external) 1.2.3.5 gateway 1.2.3.4<br />
<br />
now:<br />
ISP vlan65 (1.2.3.4) &nbsp;firewall interface (vlan?) ?.?.?.? <br />

thanks for the help.

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

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

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.
