you mean you want to use two public ip address to one server having single NIC ?
or you want to use both the ips to router and want to dst-nat the local ip to make it reachable via public network ?
please ,clarify.

No problem at all. I’ve recently spun something similar up for a customer request.
My use case was pppoe-out1 with static IP X.X.X.1 and then it had a /29 of routed IP’s Y.Y.Y.0/29 of which each port in the router (RB3011) was going to have a different LAN range but traffic coming from a corresponding public IP.
EG;
ether1 = 192.168.1.1 = Y.Y.Y.1
ether2 = 192.168.2.1 = Y.Y.Y.2

The pppoe-client (or router if you like) used the X.X.X.1
Then using src-nat rules (note not masquerade), src-address=192.168.1.0/24 action=src-nat to-address=Y.Y.Y.1
dst-nat rules are just set up as you would any other dst-address Y.Y.Y.2 action=dst-nat to-address=192.168.2.200

I think that’s what you were asking, my explanation is probably a little lacking in some details but essentially the answer is YES :sunglasses:
