I have a client who uses a Sonicwall router to hand out DHCP leases and route traffic on their LAN. I'd like to just switch it with a Tomato router, but the Sonicwall supports multiple WANs (certain traffic needs to go out on the T-1 line and others on the FIOS line). I would like to plug in a Tomato router between their main switch and the Sonicwall to do QoS. But, the Sonicwall has to remain the DHCP server. How can I make it so that: 1. LAN clients can still get their DHCP from the SonicWall, even though the Tomato router will be between the Sonicwall and the LAN. 2. Tomato can act as a router that is capable of doing QoS. Would it work to set Tomato as a Router (vs Gateway) and disable the WAN connection? Essentially, I don't want Tomato to do any NAT.
