pix routing ip to VOIP Vlan

My client has a PIX Firewall, their phone vendor put in a VOIP system and Procurve Power over Ethernet switches.  Then computers, servers and PIX operate on and the VLAN for the phones is  The computers cannot access the IP which would enable them to config certain parts of the phone system,saving a tech visit.  The Phone vendor says I need to setup the Pix to properly route the networks together.  I was not aware that the Pix could route traffic.  Here is the config

Hello mberryaz,

>> I was not aware that the Pix could route traffic

It cant! the PIX can understand some basic rouTING protocols (RIP and OSPF for example) but it can not intellegently route traffic  - your only option it to put a router/Layer 3 device behing the PIX that can make these routing decisions for you, then make that device the default inside route for the PIX


You are correct.  Your PIX isn't capable of routing traffic received on the inside interface back out the inside interface.  You would need 7.x code running on a PIX that supports 7.x (501 does not) or an ASA.  Do you have a router lying around?  Worst case, you could enable routing on a Windows machine.

What about if I replaced the 501 with an ASA 5505? could it accomplish the same goals?

This help point me on the right path, thank you
The PIX 501 with IOS 6.3 does not supprt logical interfaces.  With only one internal interface (connected to a 4-port switch) and no support for logical interfaces, the PIX can not access multiple networks.  Access to multiple networks is required to route.  The best it could do is, like inferred above, is send the packets to a router-device inside your network.

Which Procurve model?  Some support layer 3 switching which may be able to do the work for you.
mberryazAuthor Commented:
the procurve models are 2610-24-pwr and 2724
The 2724 does not appear to support L3 switching.
The 2610-24 series does appear to support it.  The HP manual is here:  http://cdn.procurve.com/training/Manuals/2610-AdvTrafficMgmt-Dec2007-59918641.pdf

The switch should support up to 16 static routes, which should provide what you need.  Chapter 7 talks of this.
