Problem with 6.** version

RouterOS Beginner Basics
1

Hello everyone,
I have this architecture that I m posting. I want to configure the Mikrotik to have a dhcp wlan that permits me to ping my top client with static configuration. I have set this configuration:

/interface bridge
add name=bridge
/interface wireless
set [ find default-name=wlan1 ] band=2ghz-b/g/n channel-width=20/40mhz-Ce
disabled=no frequency=auto mode=ap-bridge ssid=MikroTik-TRY
wireless-protocol=802.11
/interface list
add name=LAN
/interface wireless security-profiles
set [ find default=yes ] authentication-types=wpa2-psk eap-methods=“” mode=
dynamic-keys supplicant-identity=MikroTik wpa2-pre-shared-key=Try123
/ip pool
add name=dhcp ranges=192.168.1.10-192.168.1.41
/ip dhcp-server
add address-pool=dhcp disabled=no interface=bridge name=defconf
/interface bridge port
add bridge=bridge ingress-filtering=yes interface=wlan1
add bridge=bridge ingress-filtering=yes interface=ether1
/interface list member
add interface=bridge list=LAN
/ip address
add address=192.168.1.1/24 interface=ether1 network=192.168.1.0
add address=192.168.1.2/24 interface=wlan1 network=192.168.1.0
/ip dhcp-server network
add address=192.168.1.0/24
/ip dns
set allow-remote-requests=yes
/system routerboard settings
set silent-boot=no

When I try to apply it to a Mikrotik with 7.* version it works, while with 6.* it doesn t: it sets the wlan1 in station mode and delete my dhcp server configuration.
Any advice?
Thank you everyone

Any suggest?

Almost there.

There should not be any difference between ROS 6 and ROS7 in this simple network.

But …

\

  • there are no VLAN seen in your config. So remove the ingress-filtering on the bridge ports.
  • a WLAN in station mode is a client device to an other AP. You have clients to the mAP, so the WLAN should be in “AP-bridge” operation mode, as your config printout is saying.

Just wonder: there might be a requirement that your pre-shared key is minimum 8 characters long, “Try123” is too short.

Mmm…

are you sure your Client answer ping requests?
Windows drop ping requests per default untill you allow it in the (Windows Defenser) Firewall (https://kb.iu.edu/d/aopy).

Thank you both for your help

I set ingress-filtering=no and now I can see the wifi (mikrotik led blinks now and I can see the wifi network on my pc), but the dhcp doesn t work (I post you a screen)

PS: I changed the wifi key with the right requirement

Yes I don t have ping problems, the same mikrotik with 7* version it works perfectly

You only need single IP address from subnet 192.168.1.0/24 and that one should be on bridge interface.

Your architecture is not clear, and where is the internet?
Do you have one or two LAN subnets?

The config is as confused as your diagram

8

Done, now I just connected my iPhone to wifi, it assigns me 192.168.1.254 (I can see it in “leases” tab too) but i can t ping it:

Why did you change your network and config…
Did your requirements change or are you blindly listening to advice…

Please provide
a. a proper network diagram showing the equipment involved, the WAN connection and the ports with conceptually which subnets/vlans should be traversing.
b. latest config

I m sorry I didn t see your reply.
I don t have internet, I d like have a wifi network where i can connect with multiple devices (so i used dhcp server) and be able to ping and use my static device (the top client you can see in my first diagram, with static ip 192.168.1.42). Idk why configuration i set (in my first post) works in 7* version and not in 6*.
I just have a constraint, to not set the gateway in the dhcp server, so when i m connected to wifi with my smartphone, i can use my mobile data to have internet (http://forum.mikrotik.com/t/no-internet-flag-on-mikrotik/158463/6)

11

I have a static device X:

  • 192.168.1.42
  • 255.255.255.0

I want connect X to mikrotik via ether1, and have a wifi where i can connect and navigate to X via its ip.
As told in the latest topic, i don t want to add a gateway to my dhcp server to be able to use my mobile data while i m connected to wifi.

12

Thanks the contsraint noted is helpful to be aware of.
Why not just turn wifi off when you want to use data ??

13

Because i have to send data from internet in real time while i m connected to wifi network. However if i reset my mikrotik and send this configuration:

:local count 0;
:while ([/interface ethernet find] = “”) do={
:if ($count = 30) do={
:log warning “DefConf: Unable to find ethernet interfaces”;
/quit;
}
:delay 1s; :set count ($count +1);
};

:local count 0;
:while ([/interface wireless print count-only] < 1) do={
:set count ($count +1);
:if ($count = 40) do={
:log warning “DefConf: Unable to find wireless interface(s)”;
/ip address add address=192.168.88.1/24 interface=ether1 comment=“defconf”;
/quit
}
:delay 1s;
};

It freezes all:

Good information that should have been stated on the first post LOL, but we will get there.
So the internet connection is your IPhone and its connected to the MT network via wifi.
You need to be connected at the same time to the internet and the MT via wifi to pass on real time traffic from LAN device.

15

Yes, I m open to new configurations, if you have better solution

16

Someone can help me with this architecture?

Recap:

I have a static device X:

  • 192.168.1.42
  • 255.255.255.0

I want connect X to mikrotik map lite via ether1, and have a wifi where i can connect and navigate to X via its ip.
Important: i don t want to add a gateway to my dhcp server to be able to use my mobile data (for internet) while i m connected to wifi.

Adding gateway will not influence access to 192.168.1.42 from any other 192.168.1.yyy (this is local LAN, not via gateway).

Set WLAN1 in the WAN interface list. Bridge (and all it’s ports) are in the LAN interface list.
