Double NAT in my network

RouterOS General
1

Hello all,

I am facing double NAT in my network. Is there any way to remedy it?

I get public ip from my ISP,

1st NAT in my mikrotik.
2nd NAT in my client’s router.

I am using PPPoE for clients.

Waiting for answers…

The best way to solve it is routing your network.
You can route creating static routes in your router and client router or maybe you can active dynamic routing protocols like OSPF.

Adding NAT in every routers it’s not necessary inside your network. Only it’s necessary on your service provider interface.

Thank you for your reply. But I am new to the OSPF. Can you provide me the codes.

My WAN is dynamic PPPoE.
I am also using PPPoE for my clients.

What is wrong on nat at clients device? He has also full right to protect his network.

Can you suggest me something to remove double NAT?

I understand that the second device is not at your possession because it belongs to your client. Is this right?

7

Yes, it belongs to the clients but I have full access to the client’s router. They are all TP-LINK TL-WR470N.

And is the tplink able to route without natting? If not, you have to deliver public ip on its wan port. I guess you would have not enough public ips to do that. Maybe the tplink supports bridge mode…

This router is a low cost router, so It doesn’t supports bridge mode and not able to route without natting.

Isn’t there something that I can do from my mikrotik?

And none replied what you wanted to read. Because this is mikrotik forum and you need to set the tplink. Moreover it seems it is not possible in easy way with standard tplink software. Try to install openwrt or ddwrt in it and then set the bridging mode or swap the tplink for mikrotik device. Or let user to be safe without your peeping inside his network. Why you care what he has behind his own nat?

This is what a firewall is for, not NAT.

To remove double NAT in this situation, NAT must be disabled on the TP Link router, and a route would need to be setup on the Mikrotik. it sounds as though this isn’t possible on the TP Link.

Sure. Nat with firewall come together in tplink home devices.
