OK, I think I resolved this.
When I reconfigured my router, I didn't reboot it. I think then the monitoring got screwed and the router was sending out garbage.
I cleared out everything this morning from my old mrtg set up, and reapplied, and all works as expected... then I remebered I rebooted router early.
So all works oK.
Sorry for the noise.
