We have a Sonicwall TZ-200 firewall facing the internet and a Cisco 1700 router that handles routing for the two VLANs that we have. The VOIP system is on a separate VLAN than the other computers. We are looking to add a 2nd WAN connection and have the VOIP traffic routed over the existing T1 line and all other internet traffic routed over the new faster Comcast line. First of all, is this possible with our existing hardware? If so, how can I configure this? I know the TZ-200 can handle dual WAN but not sure if it can split traffic based on protocol/service. Supposedly Sonicwall NSA devices can do this, but what about the TZ? If not, please confirm what hardware I would need to accomplish this.
