I had a Edgerouter Lite die and I'm trying to configure a Mikrotik in it's place but I'm having trouble with the static IP block that was provided from the ISP.


I need to allow two of the public IP addresses to accept port 8000 based on an allowed list of IP's, each public IP routes to a different internal server. I've tried 1 to 1 NAT configurations but think I must be missing something subtle.


The connection is UFB PPPOE, no VLAN tagging and the static block is routed to our main IP.


Should I be explicitly adding the static IP info somewhere in the Mikrotik?


Any help appreciated.

No need to add the (I am assuming) /30 to an interfaces if its routed to your PPPoE you can just pick this up with nat rules to/from your server

For the mikrotik make sure MAC server and discovery is disabled on your WAN interface and also ensure Winbox and DNS and other ports are firewalled on your WAN interface.

Thanks. I'll have another look at my rules again.
It's a range but we currently only use two of them.

jm3: Thanks. I'll have another look at my rules again.

Here is an example for you


Assuming that:


* You want to port forward TCP 8000


* Your internal subnet is ""


* Your PPPoE interface to your ISP is "pppoe-isp"


* Your internal server is


* Your first IP of your /29 is 


The following syntax will port forward tcp 8000 from to


/ip firewall nat add chain=dstnat action=dst-nat to-addresses= to-ports=8000  protocol=tcp src-address= dst-address=  in-interface=pppoe-isp dst-port=8000


The following syntax will NAT all traffic to from out to the internet using instead of your PPPoE ip address


/ip firewall nat add chain=srcnat action=src-nat to-addresses= src-address= out-interface=pppoe-isp




I will also repeat my above message secure your Mikrotik WAN interface so it doesn't get hacked (as per previous post)
