I'm running several disjoint WFH people in my house...because of the VoIP and VPN traffic, I had to add a second link to my house.

Both are 100/20 cable links. (Cox)

On the recommendation of a coworker, I purchased a TL-R600VPN to load balance the two WAN's

My modems are Arris CM8200A's.

My current configuration is:

Modem  --> port 1 --> Netgear Wifi Router  --> B/G Wifi + several wired devices (1 Cisco Anyconnect User)

              --> port 2 --> Hardware VPN firewall (Meraki) --> single user Data+VoIP

In the new configuration, I'm thinking this:

Modem #1 -> port 1 --> TP WAN port              ------ LAN Port --> Netgear Router  --> existing users + 1 new user using VPN. Data+VoIP

Modem #2 -> port 1 --> TP WAN/LAN port#1  ------ Meraki Firewall

Can I connect the Meraki Firewall to another WAN/LAN port?  It so far has not liked the router and hogs a lot of bandwidth. Or should I just leave it connected to the secondary port on Modem #1 (that seems counterintuitive to me)?

Does the R600 automatically know whether the connection in a WAN or a LAN?

I am an engineer but I am not a networking guru...any insight would be appreciated!!

If anyone is curious, I chose two 100/20's instead of a 300/30 because the UP traffic will be close to using all 30, and it was way more expensive.

Thanks
