For example, you can have two VRF domains and route them across your network, both with the same IP address space but still logically separated. What I don't know, is whether you can somehow route between two VRF domains (if that's even what you call them).<br><br>For now, we are using ACLs, and for the most part they work, but it's not ideal. Putting things behind a firewall makes sense, but with multiple data centres, you have to ensure that the voice servers can communicate with each other unhindered/unblocked. There are also some issues with respect to asymetrical routing which I think is an issue for us.<br><br>Until Cisco comes up with a recommended design for putting their voice servers behind firewalls in multiple data centres, I think people will be clamoring. <br><br><br>---<br>Lelio Fulgenzi, B.A.<br>Senior Analyst (CCS) * University of Guelph * Guelph, Ontario N1G 2W1<br>(519) 824-4120 x56354 (519) 767-1060 FAX (JNHN)<br>^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^<br>"Bad grammar makes me [sic]" - Tshirt<br><br><br>----- Original Message -----<br>From: "Scott Voll" <svoll.voip@gmail.com><br>To: "<cisco-voip@puck.nether.net>" <cisco-voip@puck.nether.net><br>Sent: Tuesday, December 2, 2008 5:56:59 PM GMT -05:00 US/Canada Eastern<br>Subject: [cisco-voip] Securing Voice networks<br><br><div>I have multiple Voice networks that I would like to put behind my FWSM.

<div>Can someone give me a run down of how they are doing it?</div>
