Hi Stan,

Thanks for the reverse path filtering "relaxed" setting. That did the trick!  Linux boxes are now listening to the GrandMaster clock. 

And everyone else, thanks for all your suggestions! I know a lot more now than I did before about how to set up PTP here, and I appreciate you taking the time to respond.

Best regards,
Alan

Another option, besides firewall, is Reverse Path filtering. Setting rp_filter to relaxed (=2) may help in some situations.
