Cannot ping public wan IP from lan network

RouterOS General
1

Hi,

In the picture below (in attachments) we have routers which are on LAN networks on main router R1, like R3, R4 …
Some Public IPs are forwarded to Private IP on router R3, R4 …
We can access to this routers by using their public address from public network. But from LAN network of this routers ( R3, R4 …) we can not ping their public IP address or access them through public IP.

Does anyone know how to make access/visible to the this public ip address of the router from private LAN of router?

MkTk-R-A2 is R1 in NetworkSchema1,
MkTk-R-A1 is R2 in NetworkSchema1,
FU-MkTk-R-1 is R3 in NetworkSchema1

The exported router’s configuration would help.

You mean manage the device through their public IP address?
Did you configure Hairpin NAT?

I put supout rif file in the post.

I mean, we can access to router R3 by his public address but only from public network. We cannot access to R3 from LAN network on his side by public IP address and we cannot ping him by his public ip address from PC which is in his private LAN.

Supout is of no use (at least not for me), can you share the config (as stated):

/export file=anynameyoulike

Remove serial and any other private info

OK. RSC (export) files are now in the post.

You should delete the .rif files from the post because they contains a lot of sensitive information (everyone can view them with the online Supout.rif reader provided by MikroTik). Post the export like other have mentioned is this thread instead.

EDIT: You’ve already done that :+1:

Hi man, you solved my nightmare. Hairpin NAT was a solution. I didn’t know.
Thank you a lot.

You are welcome, perhaps you can mark my post as the solution (instead of your own post) :sunglasses:

Why? It was @pajsije who did the job on his router :stuck_out_tongue:

12

Sure, why not. I’m new here, I don’t know how to do that.

Thanks man, everyday I learn something new.

Good to hear…there is a lot to learn in MikroTik land!
