We have from ISP 5xIP public thereof 3 IP have the same GW and 2 IP different GW.
Requirements from ISP is that every public IP need unique MAC adr…
cable modem from ISP => switch connected with 5 physical ports to Mikrotik =>1xNIC on server (we have one physical server with only one NIC (5xVLAN) without possibility to add other NIC), on server Hyper-V with 5 virtual SRV (5x Exchange)
each virtual SRV need connection to the internet through 1xpublic IP every time the same IP outgoing comm./incomming comm.
We need that each WAN1, WAN2.. directs all trafic to the same physical port LAN1, LAN2 IN and OUT the same way, for example :
WAN1 to LAN1 (VLAN10) and LAN1 (VLAN10) to WAN1
