Verizon 5G Modem/Router + Eero 6: very poor VPN speeds

I’m set up using the newest Verizon 5G modem/router connected to an Eero 6 mesh router. When I’m connected to the Eero gateway, I get great download and upload speeds, basically equivalent to connecting to the Verizon router. Plus I get much better range throughout my home via the Eero extenders.

However, when I connect to my work VPN, the download speed craters. Once I’m on the VPN, the download speed through the Eero is ~25% of what I get directly on the Verizon router.

Any configuration tips on either the Verizon Modem/Router or the Eero network to keep reasonable VPN speeds? Thanks!

My company VPN speed is about 1/5th to 1/7th the speed of all other traffic.

Does the behavior change if you connect to the eero gateway vs a leaf node? If no, then are you in a double NAT? It sounds like you might be based on your description.

Possibly the VPN could lose some efficiency with multiple NAT traversal. Apparently you can put the Verizon device in IP Passthrough / Bridge Mode:

Assuming that’s the device you have, might be worth a try.

I expect slow speeds over VPN. But I get ~30 mbps over VPN connected to the Verizon modem/router and only like ~5 mbps over VPN connected to the Eero.
