I want to route public IPs subnet behind MikroTik router (RB1200) with masquerading of MAC-addresses.
First interface of my router connected to datacenter core router, 2nd port - to my local network. In local network I have servers with public white IPs on network interfaces (NOT private subnet).
I want to route/gateway this addresses to datacenter network, but I cant send MAC-addresses of this interfaces to DC network, because on DC core enabled port security/mac filtering.
I cant use classic NAT, because I need to have real IPs on servers interfaces, not private IPs.
According to this, both known by me variants (NAT and bridge) seems invalid.
How I can do that?
