I have one little problem and i hope that you'll be able to help me. First let me say that you'll need picture on the link http://tinyurl.com/l3v5w3 in order to understand my problem.
PC1 does not have wlan card so i connected it (with ethernet cable) to the Edimax wireless AP which is on client mode. So now i was able to connect to the wireless ADSL router (Zyxel 660HW) which is located in the next room. Zyxel660 is connected to the Planet WAP4000 wireless AP (keep in mind that this is only layer2 device) located on the roof of my building.
In the center of the network there is Mikrotik PC with two wlan and one ethernet interface.
1. wlan1 card is connected to the omnidirectional antenna. This interface is in ap mode and serves other clients
2. wlan2 card is connected to directional antenna (directed towards PLANET WAP4000), and this interface is in station mode
wlan1 interface and ethernet interface are added to the bridge1 interface under the same ip address 192.168.55.1/24, and wlan2 interface has address 192.168.56.2/24 and connects to the PLANET WAP4000.
PC3 is connected to the ethernet mikrotik interface, and other clients (PC2) are connecting to the wlan1 mikrotik interface (55.0/24 network)
On mikrotik i added command: ip firewall nat add chain=srcnat action=masquerade out-interface=wlan2 in order to be able to ping PC1 from PC2 (becouse WAP4000 is only layer 2 device), so mapping of 56.0/24 network to 55.0/24 network is necessary
I can ping PC1, from PC2 and PC3 as well as all other network devices in the image, however when i try to ping PC2 from PC1 ping
fails. Why is that ? What i'm doing wrong ?
From PC1 i can ping everything except PC2 or PC3. Please help.
