Very basic wireless scenario

RouterOS Beginner Basics
1

Hi all, this is my first post, I hope don’t disturb all with my basic level.
I’m very new in the Mikrotik world and I want to start with a very basic scenario in my home to test and learn how works this hardware and the routeros software.

The scenario it’s as follows:

( Internet ) — (RouterDSL) — (OpenBSDFirewall_DHCPServer_DDNS) — ( SWITCH ) — (Mikrotik RB153_w/2xRB52)
|
( MiniLAMP Server )

Ok, I have the Mikrotik RB153 with RouterOS 3.10 recently installed with Netinstall and I think is working well (I have a winbox console on it).
I want to:

a) Work with two wifi laptops in the MiniLAMP Server as transparent as I can access all the services in the same Lan Net.
b) Give my neighbours free access to Internet in the more secure way and scheduling the time they can use it.
c) In a future stage, drop the OpenBSD Firewall (is a noisy machine) and use the RB153 as Firewall with the same configuration (DHCP Server, DDNS client, DNS Forwarder, etc..).

The RouterDSL is on 192.168.1.0/24 and all my net is working on 192.168.0.0/24 now (with a boring linksys wrt54g ), the minilamp server has a static address (192.168.0.100) and the laptops obtain his address from the OBSD Firewall with DHCP.

And this is my little home scenario, how can I start working on it?

Thanks for all the help, and sorry about my buggy english.

you can read here about how to set up the wireless interface
http://www.mikrotik.com/testdocs/ros/3.0/interface/wireless.php

for wireless, set up WPA or WPA2 security settings

simple routed network will work nicely

Thanks for the quick reply! I have read the doc and I think I understand it.

Ok, I have setup a wlan interface as ap-bridge with a bssid “javino” and with a security profile working with a WPA-PSK password.

But, I can’t obtain an IP address from the DHCP Server hosted on my OBSD Firewall, I think I need to make a routing filter or rule to success the initial config.

How can I make this, maybe a NAT rule?..

Sorry again for my nerd level… I’m a novice in this device.

Hi there,

I think we share the same problem. I have a dhcp server and mikrotik 2.9 as AP. when WPA-PSK is enable, my clients couldn’t get IP. but if I disable WPA-PSK, they get it. Is there any solution for this? currently, I have to use hotspot as temporary solution. Anyone facing the same problem and solved it please help.

thanks.

I have seen this on some Atheros based drivers.
Check for an updated driver.

I use the MikroTik Atheros Windows driver and it works GREAT..

I have also seen this with Centreno based systems… Update the drivers…

Ok, I’ve solved all my basic wireless scenario questions with a lot of work in two long long long nights… Now I Have the following scenario owned by my RB153 router.

(INTERNET) ↔ (DSLROUTER) ↔ (RB153+2xR52Atheros) <—> (LAN_SWITCH) ↔ (LAMP_SERVER)

And two laptops working from one of the R52 Atheros Wlan, but I have a problem setting up the DHCP Server in the RouterBoard, when I set up in the wlan iface, it doesn’t give me a valid ip address in the LAN, and viceversa… when I setup in the ether1 interface, the wlan clients don’t got their dhcp ip.. A little more explanation:

LAN iface = ether1 (192.168.0.1/24) - dhcp-pool-ether1 = 192.168.0.20-192.168.0.30
WLAN iface = wlan1 (192.168.10.1/24) - dhcp-pool-wlan1 = 192.168.10.20-192.168.10.30
WAN iface = ether2 (192.168.100.2/24) - STATIC ADDRESS in the same net of the DSLRouter

The problem is that I want to share the same net in the wlan interface and the ether1 interface (the lan side of the RB153). I don’t know I must use the same dhcp server for both interfaces, or two dhcp server sharing the same pool… I’m a little bit confused with this…

What can I do?

Thanks for all the help…

You can bridge both the wireless cards along with the ethernet card.
Assign an IP address to THE BRIDGE.
Set up DHCP to use the BRIDGE as the interface.

This will do what you are looking for…

Ok, thanks csickles and janisk! Works perfectly …

That’s the last step for sure!. I want to setup a hotspot in the free WLAN interface (wlan2) for sharing a queue of my DSL Broadband access to my neighbours (3) in a scheduled time, that’s only the time I don’t stay at home, and with the highest security level.
Of course, I don’t want to give access to my LAMP Server (see the posts above) or laptop’s, they could find my Britney’s photobook and there’s no place for me in this neighbourhood with this reputation… :laughing:

Thanks for all the help, I’m planning to make a step-by-step wiki or howto and I want to share with all the users, there’s a open wiki or blog to write out?

Cheers.

Hi all, I’ve setup my HotSpot with reading some info in the forums, but when I’m connected throught the hotspot I can access my LAN network and that’s not the idea.

I want to block all the traffic from the wlan2 (hotspot iface) to the lan net or wlan1 net (I have a bridge with both).

How can I make this?

The address of the hotspot is 10.5.50.1/24 and the DHCP server give from 10.5.50.10 to 10.5.50.20.

I want to limit too the ports and the max download/uploads rates.

Can someone help me or give me some reference docs?

Thanks for the help
