Depends on how you have the switch configured.<br />

Typically, voice traffic is segmented onto a separate VLAN.<br />

These are SMB type switches. &nbsp;16 port non management 10/100/1000 Linksys.<br />
<br />
My concern is having the non firewalled 10.x leg intermixed with the 192. leg.<br />
<br />
Should I be concerned?

a bit vague. &nbsp;<br />
<br />
The real issue is would it open the network up to outside attack as the 10. leg is internet facing and the 192. leg is internal behind the firewall.<br />

I have a new situation where the phone guys need to start using the LAN wiring to support their phone system and VOIP.<br />
We have a dual nic SBS2003R2 STD. &nbsp;Lan is 192.168.16.xxx and WAN is 10.0.0.xxx.<br />
<br />
Question is does firewall security get defeated is both ip segments are running around on the same switch.<br />
<br />
Thanks<br />

LAN VS WAN on same Switch

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
