Decided for now to have 2 routers and a DHCP server that directs phones to one, workstations to the other.

Each VLAN has a different DHCP range.  In the router with your sub interfaces simple create two different access lists.

Create one access list for each subnet.  Enter permit statements for the subnet you want and apply it to the appropriate interface.

This is the same method used to separate public WIFI from local network.

I am only familiar with "simple" routers.

What are "sub interfaces" and "access lists"?

How does 1 router connect to 2 WANs?

Will You Be GDPR Compliant by 5/28/2018?

GDPR? That's a regulation for the European Union. But, if you collect data from customers or employees within the EU, then you need to know about GDPR and make sure your organization is compliant by May 2018. Check out our preparation checklist to make sure you're on track today!

Policy based routing (PBR) is used to define your requirement. Ip's belong to vlan1 should go to gateway1 and ip's belonging to vlan2 should go to gateway 2.

If you know the commands already, should take 5-10 mins to configure.

Else, you can read over to any doc available in internet (including cisco.com), should take 1 hr max.

Let us know, if you need help with the doc.

Best,

ok I thought this was a working dual-wan you were changing.

So you need to make it dual wan, then add vlans, then split the traffic?

can you provide router type and intent?  Based on your last comments I  am not sure what the goal is?

FWIW I am adding VOIP phones to an existing network. My client rents space in an office building that provides internet access via T1 lines. The building mgt wants us to keep the VOIP traffic off the T1 lines. My idea is: we provide our own DSL line to handle the VOIP traffic. The workstations will continue to use the T1 access. Hence the desire to connect to 2 WANs.

what is the router you are using?

I don't have a router in mind. That is part of my research - to find suitable routers.

The current router is a Linksys Broadband Firewall Router BEFSX41.

2 VLAN's with 2 WAN's = one router with at least 3 (2+1) interfaces, or 2 routers.

So it is possible to connect 2 routers to 1 switch and have each serve a VLAN?

Well a good price for one is an RV082.  You do not need to be a router person, it's a web interface.  It has dual WAN's built in and it does vlans.  It also has 8 switchports and they can all be assigned to a different vlan.  If you need more ports you can hang a switch off of it.
