Multiple WAN IPs with same gateway

Hi guys,

currently my mikrotik is connected via l2tp to another one to interconnect my datacenters.

Now, i want to use the mikrotik which is configured as l2tp-client to use another wan ip address to use it for natting traffic with dst-nat to virtual machines.

Following a short overview of the ips:

  1. IP: 88.***.8.89/29 on interface ether1
    with virtual mac

  2. IP 88.***.8.88/29 on interface ether5-88
    with another virtual mac

GW of booth ips is 88.***.8.65

If i set the second ip, the first one will become unreachable and the vpn-connection will terminate, because router os will add another default route via the second interface.

So i want to use the first ip only for vpn interconnection and management of router os and the second one only for NAT.

Can someone assist here?

Greetings
Philipp
