Hi,

Here is my situation, it's really urgent for me so pleas help.

I have 2 routers:
Router1 - 192.168.4.0/24 which is doing NAT and other stuff...
Router2 - Handles multiple IP ranges 192.168.0.0/24, 192.168.1.0/24, 192.168.2.0/24

These two routers are connected. Situation is that all the computers from 192.168.0.0/24 range I see as one IP address on this Router1.
I would like to see each device individual IP address on the Router1.

Can anyone help me on how to do that?

Probably you are making some nat on Router2. Remove it so it only routes.

I'm not sure you understood my question. Maybe I didn't described my network config and what I want properly.

Here it is...

Main router with 2 WAN connections:
Router1 - 192.168.4.0/24


Router2 - which is connected to Router1 and has IP 192.168.4.X
Router2 manages 3 different IP ranges on 3 different interfaces.
ETH1 192.168.0.0/24
ETH2 192.168.1.0/24
ETH3 192.168.2.0/24

Both of these routers and many servers are connected to one switch and all the servers have IPs 192.168.4.X

Behind ETH1 (192.168.0.0/24) interface I have a lot of devices (computers, phones, etc).
The problem is that for ex. one of these computers is accessing for my domain server (192.168.4.X) and I can't see his real IP of that PC (ex. 192.168.0.55), but I see him/all of them as 192.168.4.X.

How can I make it so that I see individual IP of every computer connecting to my server on my Router1?

I second CyberTods suggestion.
Post a compact export of your configs (of both routers) and we will have a look.
It still seems that router2 is connected to your 192.168.0.0/24 subnet on ether1 with some default settings active, i.e. NAT/masquerading.
This would explain your observations.

Ok here are the configs.
I've removed all the information that public shouldn't see.

I am assuming central.rsc is your 2nd router.
You have this rule :
This is exactly the nat you must disable. Otherwise everything leaving the router through ether12-WAN is masquaraded with the router's ip.

OK. So when I disable this rule I will see individual IP from all the PCs (172.20.0.0/24) connecting to my domain controller (172.20.4.4) ?

I've tried this and it's not working.

So again... All I want is to see on ma Router1 computers connecting from Router2 with their real IP addresses.

Router1 - 172.20.4.254

Router2 IP address - 172.20.4.31
Router2 manages 3 subnets (172.20.0.0/24 , 172.20.1.0/24 , 172.20.2.0/24)

Computers connecting from 172.20.0.0/24 that are connecting to my DC...I can't see their individual IPs like 172.20.0.10, 172.20.0.11... etc.. but I see all the PCs coming from one IP 172.20.4.31. That is the IP of my Router2.

How can I see all the PCs with their individual IP address???

Thank you in advance.

Please, please is there anyone that can give me a solution on this.
I think I managed to describe what I want.
If somebody didn't understand me or something please ask so we can talk more on this.
I really really need the solution.

Thank you in advance.

Create a neutral net between the routers and route the traffic both ways thru it without using nat or masquerade.

It's easy ...

You have a rule on router 2 (core firewall) that masquerade all traffic that goes to router 1 (internet gateway). Disable it.
You must also put 3 static routes on router 1 ponting to router 2 gateway, one for each subnet behind it.

.......

I've readen your rsc and I can't undesrtand what are you trying to do with all this nat rules. I supose that you're working on someone's else cfg files and you want us to do the same for you, but I'm so sorry, it is not easy without a draw of the whole network and more knowledge about the project.

It looks like you are trying to do a two firewalls schema, with dmz to core firewall and inernet to dmz IP napt, two gateways and a Ipsec VPN to somewhere, but I'm not sure .....

flipk12 thank you for your reply very much. I will give it a try and let you guys know.

I'm not doing configuration for someone else. These are actually configs from company's routers where I work.
My colleague that usually does the administering Mikrotik is not here and I need to do this.
I'm a newbie to network and Mikrotik in general, but I'm learning about networks and hopefully I won't ask these kind of questions in future.
I'm sorry for asking some trivial question, please be patient with me because as I said I'm new to computer networks.

Thank you very much for the help.

Regards

No, it is not a trivial question ..... so we have to know the whole problem to be able to help you.
Yes, your college is someone else, not you, is that i'm trying to say. You're trying to change a cfg that you don't understand, but you know the network, what you are trying to do and we don't.
Don't worry, ask all what you want.

Just to inform you guys that I've solved this by following your instructions.
Thank you all very much, you have been very helpful!

Congratulations!
