Mikrotik with 2x Wifi - novice question

Network2Explore · Thu May 02, 2024 6:10 pm

Hi,
i'm tring to setup a RB952Ui with one Wifi 2,4 Ghz to connect to a access point, which is a internet router. The other Wifi 5Ghz for clients to connect.
The first Wifi has a DHCP client running and the second a DHCP server. This has worked so far.
With the script below it is possible to connect to the mikrotik using the client Wifi and it connects to the internet ap.
DHCP Server gives IP to clients but there is no connection to the internet. Internet is pingable within the mikrotik.
Probaly i did not understand the bridging between the two wireless networks.
So where did i mess up?

/interface bridge
add name=bridgeLAN
/interface wireless security-profiles
set [ find default=yes ] supplicant-identity=MikroTik
add authentication-types=wpa2-psk eap-methods="" group-ciphers=tkip,aes-ccm mode=dynamic-keys name=profileLocal supplicant-identity="" unicast-ciphers=tkip,aes-ccm \
    wpa2-pre-shared-key=###
add authentication-types=wpa2-psk eap-methods="" group-ciphers=tkip,aes-ccm mode=dynamic-keys name=profileRelay supplicant-identity="" unicast-ciphers=tkip,aes-ccm \

Wlan2/Wlanlocal is part of the bridge (with ether2-5), Wlan1/Wlanrelay is not.
So you don't seem like bridging the two WiFi, but rather routing

, and you have a srcnat masquerade with out interface Wlanrelay.
But you seem like not having added routes, what is the output of:
/ip route print
?

The routes are like this. IP 192.168.88.1 ist the internet router from which the mikrotik got dhcp adress on wlanRelay.

Flags: X - disabled, A - active, D - dynamic, C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, B - blackhole, U - unreachable, P - prohibit

Hi,
thanks for the reply.
After some investigations, I figured out the part of the config:

add address=192.168.3.0/24

in the section

/ip dhcp-server network

has to be deleted and it works.
