Re: [Mikrotik] pseudobridge polled devices question

Sounds like a good plan.  The only thing I would change is instead of
802.11abg just use the 5mhz channels.  You will have minimal interference
problems, better foiliage penetration at the loss of bandwidth (though I'm
sure those solar units don't need anything more then a few megs...)

Re: [Mikrotik] pseudobridge polled devices question

2009-05-04 Thread David Smith 
Yes, I really would not like to kludge something together. 
Most of the time, we install wireless networks to backhaul video to a central 
location across water towers and other assets across Strix which acts as a 
"distributed switch" and we dont run into the 802.11 edge issues. 
This deal is a little different. I need some edge type devices.

Here is more detail on the setup:
The goal is to collect information from approx 300-400 solar arrays. Each array 
has a charge controller with a serial port. This is the reason for the serial 
to wifi adapter. Each adapter can have a unique ip, or be dhcp etc. The 
adapters do not send information, they are polled. They will all be polled 
hourly for information to help keep track of charge, battery life, etc to ease 
maintenance costs. 
All of them are in a circle approx 5 miles radius. At the center of the circle 
is a 150' tower with 3 120deg sectors on 802.11a with a Strix unit at the base, 
and the default gateway.
So, in the field, you will have say approx 150 "hub" locations that have 2 or 3 
solar arrays around it powering various devices. 
I am planning on putting a rb433 at each of 150 locations with a 802.11a for 
backhaul to the tower, and an 802.11bg for the 2 or 3 serial to wifi adapters 
to connect to locally. 
Also need client coverage for laptops etc.

We bought a rb433 with the 2 cards in it. I got that working ok, but then once 
i had to setup pseudo, i started asking what-ifs.

I can subnet each "hub" location if needed, say 172.26.x.x for each location, 
172.26.0.x for main network. I could do NAT, but each wifi to serial listens on 
the same tcp port, so i would have to manually set the ports, would rather not.
Will the mikrotik handle DHCP relay? 

I know this is alot, just trying to get my ducks in a row before my goose is 
cooked ;)
thanks,
ds

Static ARP will not fix this.  The problem is related to 802.11 (as you
have pointed out in your question).  IF you run a netwatch script to
ping the remote devices from time to time, it may help.

In this case, the best solution is to route or NAT (if you have that
option).  Layer2 will be broken for you due to the network
configuration.

Looks like you are right:
*station-pseudobridge* - wireless station that can be put in bridge. MAC NAT
is performed on all traffic sent over the wireless interface, so that it
look like coming from the station's MAC address regardless of the actual
sender (the standard does not allow station to send packets with different
MAC address from its own). Reverse translation (when replies arrive from the
AP to the pseudobridge station) is based on the ARP table. Non-IP protocols
are being sent to the default MAC address (the last MAC address, which the
station has received a non-IP packet from). That means that if there is more
than one client that uses non-IP protocols (for example, PPPoE) behind the
station, none of them will be able to work correctly

Still, you should not have problems with ARP with good links to your
stations on wlan2.  If you really care about it add netwatch to the rb433 to
them every 2 minutes.  This will leave the MACs in the ARP table.

Re: [Mikrotik] pseudobridge polled devices question

2009-05-04 Thread Josh Luthman 
Looks like you are right:
*station-pseudobridge* - wireless station that can be put in bridge. MAC NAT
is performed on all traffic sent over the wireless interface, so that it
look like coming from the station's MAC address regardless of the actual
sender (the standard does not allow station to send packets with different
MAC address from its own). Reverse translation (when replies arrive from the
AP to the pseudobridge station) is based on the ARP table. Non-IP protocols
are being sent to the default MAC address (the last MAC address, which the
station has received a non-IP packet from). That means that if there is more
than one client that uses non-IP protocols (for example, PPPoE) behind the
station, none of them will be able to work correctly

Still, you should not have problems with ARP with good links to your
stations on wlan2.  If you really care about it add netwatch to the rb433 to
them every 2 minutes.  This will leave the MACs in the ARP table.

Yes, but the pseudobridge only presents ONE MAC address to the network site - 
it's own. The pseudo then answers as a proxy for any MAC addresses behind it 
(the ones in its table). What happens when these entries time out?
WDS would be the switch equivalent, not pseudo.
I cant implement WDS.

Re: [Mikrotik] pseudobridge polled devices question

2009-05-04 Thread David Smith 
I am just learning that this may be an issue, so bear with me.
My understanding of pseudobridge is that it is basically a NAT for MAC 
addresses.
So, the pseudobridge MAC NAT table would only be populated with MAC addresses 
from devices behind the pseudobridge that had initiated some sort of traffic 
that went out the bridge. 
If that is the case, then would not the MAC NAT "table" time out, or then 
entries expire after a period of time? BTW, what is the default time, and how 
to populate the table with static entries?
Thanks for your patience,

David Smith

Shouldn't have a problem...if you're really concerned you can put the MACs
in staticly but if you have a delay in ARP resolution then you have a poor
link.

[Mikrotik] pseudobridge polled devices question

2009-05-04 Thread David Smith 
I have a rb433 with (2) 52 radios.

One radio (WLAN1) is 802.11a and connects to an ap which is connected to
the default gateway.

The other radio (WLAN2) is 802.11bg and allows client access with 1
SSID.

WLAN 1 is Station pseudobridge, and WLAN2 is ap-bridge.

On the WLAN2 side, the clients consist of 802.11bg to serial terminal
servers (up to 5 of them associated). (These are the same as serial to
Ethernet, just wifi enabled.)They all have static IP address on the same
subnet as the rest of the network, as is the default gateway.

These devices are polled via IP address ONCE every hour from a remote
site using a VPN connection to the default gateway.

So, using pseudobridge, will I have an issue polling the devices behind
the 802.11bg radio since traffic is initiated only on the default
gateway side?

Will the arp table entries on pseudobridge expire is my concern.

Thanks!
