Normis,

I have found the same challange.
I have seen no one answered btw.

each interface in a single bridge
bridge filter to block traffic from each interface (needed to separate each dhcp)

Remember db is logaritm scale not linear. Card power referred to 1mW: 10dbm = 10^(10/10)= 10 mW 13dbm = 10^(13/10)= 19.95 mW 14dbm = 10^(14/10)= 25.11 mW 15dbm = 10^(15/10)= 31.62 mW 16dbm = 10^(16/10)= 39.81 mW 20dbm = 10^(20/10) = 100 mW With your configuration you have. 28dbi gain antenna absolut...

RB500 with daughterboard

NMP5354 & CM9 cards for APs

I'm the dubt that with the mixing of NMP5354 and CM9 the RB

maxfava

does someone have some news about that very strange problem ? I have downgraded to RouterOS 2.9.3 and did a /system reset. All seems to be ok now. I'll make others tests (upgrade and see the difference with the same antenna, same cables, same CPE). MimiFleX, I'm facing the same issue from 1 month. ...

maxfava

From my experience,
to have better bandwith use separate RB for each sector.

After infinite trials, I have found a different behaviour changing the channels.

/ip firewall filter add chain=forward protocol=tcp tcp-flags=syn connection-limit=300,32 action=drop src-address=192.168.1.1

In this configuration customers communicate in layer 3 with edge router.
Tell me if I'm wrong, PPPOE connection are not allowed in this scenario, only PPTP are routed to the back bone. Or there is a way to bridge only the PPPOE request to the edge between two network?

maxfava

jd6strings,
have you tried to insert a firewall rule that drop invalid connection, accept related and valid? instead of accept all?

I tried this yesterday and at first time it works, but response will be tonight after 24 hours.

maxfava

if you use bridge you will implement a large network. If you use route you will separate the network between the routers. in WDS you will use bridge between the WDS links. Client will be in this bridge. But you can route this network or client could be connected to an Virtual access point or assigne...

At the end I used bridge, since I need to serve PPOE service to customers over Wlan.
Also on the bridge filter I can manage all protocols trought the bridge.
I think that there is not possibility to redirect PPOE calls is it true? or do you know how to?

maxfava

I understood the issue

the problem was that on the target machine it was not set the default getaway. so the answer packet was not correctly routed to the caller.
Is it correctly behaviour for a router?

Only for accademic question. In Wireless environment, it better to use a router or a bridge? For example, (basestation/NET 1.0/25) --> Repeatare ---> client /NET 1.129/25 Repeater would be a router or a bridge? From TCP basic. In router I will separate the varius WLAN at MAC address layer.

From the routerboard manual the max total power consumption is 14 W comprensive of mPCI cards.

Your 48V / 0.6A provide 28W (P=V*I).
It is double of what you need.

I suggest to use 48V POE.
I planned to use it for my new network based on RB.

Power in Watt = Voltage * Current. mpci output power is 400mW @ 3.3 V. means that total power is 0.4 while current is I = P / V = 0.4 / 3.3 = 0.12 A The power is the same in input. Means that with 48 V the current is I = P / V I= 0.4W / 48 V = 0.008 A or 8 mA. 48 V POE supply until 48W means 1 A. th...

antenna out power not depending of the POE 48 or 18 V.

take in care that the use the same channel is a risk. But you can use non-verlapping channels with the 3 APs 10 meters distant. for example 1 3 6.
instead of 1 6 11

OK but simultaneous, what does it means:
total connection opened?
connection opened per sec?

in some case client router hang up because the number of connection opened is too high.

What do you sugest?

Is this rule limit new connection opened at the same time? or total?

The manual is not very clear.

You have to use a scripting that insert simple queue specified for p2p when a customer log in.
