Modem TP Link as A Router

So, you have an issue that there is max mac-address limitation on ZTE's DSLAM that can't be raised more than 16, what's the feasible solution for that?

I'd give you one of them. It is, change the modem to act like a router.

Here's some example for that,

Assuming that we've got PVC 0 with VPI 0 VCI 33 for modem's IP management and PVC 1 VPI 1 VCI 34 for the services

And voila, your modem will act like a router though the side effect, the modem's management IP will not work anymore.

Hope this useful.
