Is my Bob Smith termination valid for Ethernet 100Mb/s?
The resistors on the cable side are supposed to terminate each pair being treated as one "wire". The purpose is to reduce EMI and they do not functionally affect the actual signals. The impedance is not so well defined. With 20 years of experience, the magnetics nowadays with built-in common mode chokes are effective such that those terminations do not make much difference.

The resistors on the driver side of the transformer are for terminating the differential signals. Those terminations are critical.

On your schematic, the R7 feeding the two center taps (pin 2 and 7) let open an unnecessary coupling path between the transmit and receive. I don't see why you would want that.
