Multiple WAN IPs with same gateway

RouterOS General
1

Hi guys,

i want to use 2 public ip addresses with the same gateway.
Following an overview:

IP1
88.***.8.89/27 used for MGMT and VPN-interconnect to another mikrotik

IP2
88.***.8.88/27 should be used for NAT ports only

Gateway: 88..8.65
Network: 88..8.64
Internal Interface is: ether2 and ether 3-4 for other ip-ranges
Main-Internal IP: 192.168.100.1/24

I’ve already trie multiple tutorials with “mangle” from the forum and internet, but only the first ip is reachable or if i try something else nothing will work.
Additionally i’ve tested the new ip: ..*.88 with anther vm, so the IP is working correctly.

Can someone assist here?

“Multiple tutorials” doesn’t give a clue of what you’ve actually configured.

Firewall mangling is incompatible with firewall fasttracking, do those tutorials mention this fact?

Post your configuration following the guidelines in my automatic signature. You should actually not need any firewall mangling to use one public IP address to access the device remotely and another one in the same subnet for NATing the LAN.
