Then on the transmit side, there is nothing specifically incorrect in a device modifying the Source Address of the packet sent from a Transparent Clock within the scope of IEEE 1588 and this would be needed in order to indicate that the device has effectively created a new packet - however, the function of the node is still that of a Transparent Clock. >
There would be all sorts of violations if you change the Source Address. NAT is bad enough without some other router also diddling with addresses. Don't do that. Danny _______________________________________________ TICTOC mailing list [email protected] https://www.ietf.org/mailman/listinfo/tictoc
