Replacement of IP/MAC source address

RouterOS General
1

Hello

I would like to use a router RouterBOARD 450G to replace IP and MAC source address in to multicast ethernet frames.

Detailed description :
Stream 1 with address source A to destination MC1 shall become source C to destination MC1
Streem 2 with address source B to destination MC2 shall become source D to destination MC2

A, B, C, D, MC1, MC2 are for IP and MAC address.
The IP class for A, B, C, D is private (class C)
The IP class for MC1, MC2 is for multicast (class D)

                Router 450G
               |-------------|
SRC:  A  >     |             |     > SRC  : C
         >-----x[eth1] |eth2]x----->
DEST: MC1>     |             |     > DEST : MC2
               |             |
SRC:  B  >     |             |     > SRC  : D
         >-----x[eth3] |eth4]x----->
DEST: MC2>     |             |     > DEST : MC2
               |             |
               |-------------|

Eth5 is used to manage configuration of the router.
Each stream must be independent of each other.

I managed to change the MAC source address thanks to bridge features.
But I have not been able to change the IP source with NAT features.

  • Could I use a bridge and nat with the same ports ?
  • And in general way, could you provide some information in order to configure the router for replacement of IP/MAC source address ?

Thanks you.
