同一 ISP 接口上的多个公共 IP

Question

I'm looking to build a 4 public IPs NAT. I've been told that MikroTik routers are capabile of assigning public IPs for each LAN port you configure.

My ISP provides 2 static IPs but I need two more. I would buy any MikroTik router that is able to make that happen through VIP...

Any recommendation for an affordable model?

Answer 1

If your ISP provides only 2 IPs, you cannot pull 2 more just because of some "magic router". All MikroTik routers have the same functionality, so any model you like will do what you configure on it.

There are no "LAN ports" in them, every port can be LAN, WAN or whatever you call it - functionality depends on configuration.

There can be any number of statically configured IPs on any interface of the router if your ISP provides them.

Answer 2

Example eth1 IP Address: 10.201.0.2/28, ~ gateway: 10.201.0.1

eth2 IP address: 10.200.0.112/24, ~ gateway: 10.200.0.1

eth3 IP Address: 192.168.51.1/24 //gateway Client ISP 1

eth4 IP Address: 192.168.52.1/24 //gateway Client ISP 2
