In order to let things clear, let me put an example (I know this could be quite stupid, but I have to report this to my boss :) )

There is no command to avoid this and send PC A source MAC address unmodified thru WAN link to PC B, correct?
Let me give you the context. We are using Cisco Contact Center with call recording and monitoring. It seems that it does not work when sending packets in different LANs thru a WAN link. The problem is that for recording, the system uses the source MAC address of the softphone (in this case, the PC) and that is changed in the routers.
