Transparently Bridge two Networks 1

Transparently Bridge two NetworksRemote networks can be easily bridged using WDS feature of MikroTik RouterOS™. We will show it for the casewhen the networks are connected through Atheros wireless interface. Using EoIP, this can be extended to any othertype of interfaces, like PPTP and CISCO/Aironet. WDS works only on Prism and Atheros based cards.Let us assume the following network setup:

^^Please ignore the AP; Wlan; LAN ip, all of them is not been use in this setup, photo just for reference.^^Follow the steps below to create transparent bridge using WDS:1. Create a bridge interface on AP and add ether1 interface to the bridge in WinBox

Transparently Bridge two Networks 2

or in console

[admin@AP]> interface bridge add name=wds-bridge

[admin@AP]> interface bridge port add interface=ether1 bridge=wds-bridge

Do the same on the Station, and add ether1, wlan1 interfaces to the bridge in Winbox

Transparently Bridge two Networks 3

or in console

[admin@Station]> interface bridge add name=wds-bridge

[admin@Station]> interface bridge port add interface=ether1 bridge=wds-bridge

[admin@Station]> interface bridge port add interface=wlan1 bridge=wds-bridge

2. Make sure you have communication between MikroTik routers, i.e., one router is configured as server (AP), theother one as client (station). Configure wireless interface wlan1 on AP in WinBox

or in conslole

[admin@AP]> interface wireless set wlan1 ssid=MikroTik frequency=5805 mode=bridge disabled=no

Do the same configuration on Client wireless interface (wlan1) in Winbox

Transparently Bridge two Networks 4

or in console

[admin@Station] interface wireless set wlan1 mode=station-wds ssid=MikroTik disabled=no

3. Create wds interface on AP and add the interface to the bridge in WinBox

or in console

[admin@AP] interface wireless set wlan1 wds-mode=dynamic wds-default-bridge=wds-bridge

4. Check whether the WDS link is established in WinBox

Transparently Bridge two Networks 5

or in console

[admin@AP] interface wireless wds> print

Flags: X - disabled, R - running, D - dynamic

0 RD name="wds1" mtu=1500 mac-address=00:0B:6B:30:B4:A4 arp=enabled

disable-running-check=yes master-interface=wlan1

wds-address=00:0B:6B:35:E5:5C

4. Add IP address on AP in WinBox

Transparently Bridge two Networks 6

or in console

[admin@AP]> ip address add address=10.1.0.215/24 interface=wds-bridge

And on Station:

[admin@Station]> ip address add address=10.1.0.216/24 interface=wds-bridge

5. Test the bridge by pinging from 10.0.0.215 to 10.0.0.216. Note, that the bridge needs 10...30s to learn addressesand start passing through traffic.NOTE: If not using NAT/MANGLE nor anything doing with conntrack, remember to turn of it at both link ends.In the console:[admin@xx]> ip firewall connection tracking set enabled=noThis will help you get the full bandwidth the wireless link can achive freeing the CPU load.
