I have a test setup of 2 identical RB133c+SR9+ 12db Rootenna units.
I want to test SNR, frequency changes, signal strengths, VPOL vs.HPOL etc etc.
The 2 units see each other through the radios just fine, one in bridge mode and the other in station mode and also using bridge+WDS on one and station +WDS on the other.
The problem I’m having is that I can’t ping the other from either side.
I’m using 192.168.1.xxx/24 addresses on both ether1 and wlan1 on both units, but can’t get a ping through to either interface on the remote unit when connected by RF. Pinging either interface from my connected laptop results in steady 3ms times. What am I missing here, or is it not possible to get pings through with Level 3 and not having one unit in AP or AP-Bridge mode?
Thanks for any help.
You need to be more specific on your config as well as what you are trying to accomplish.
In order for packets to route you must have differnt subnets on all interfaces.
If you give each WLAN interface an address (ie. 10.10.10.1 and 10.10.10.2) then add an eoip tunnel interface to tunnel to the ip address on the other side of the link (done on both Routers) then bridge the ethernet interface and eoip interface, you should have a transparent bridge.
Interesting. It seems too complicated with too much overhead just to get a ping through with 2 devices on the same network. I can understand the rational for using EoIP to connect 2 networks, so are you saying that the WLAN interfaces on the 2 devices can’t be on the same subnet and will have to use a UDP tunnel on a created interface to talk to each other and that the ethernet interfaces cannot be on the same subnet as the WLAN interfaces and have to be bridged?
Is this actually what happens under the hood with an AP in bridge mode and a client radio in bridge mode? I guess it must be- so pardon my ignorance- and thanks for the reply.
Sorry for the thrashing about. I’ve been a cabinetmaker for 35 years.
It seems that using WDS would work as well if not better than an EoIP tunnel-but I see that giving all my interfaces addresses in the same subnet wouldn’t allow any packets to move between the 2 devices.
The thing you have to keep in mind, is that this is a true router you are dealing with.
If you want TRUE transparent bridging out of the box, then use Proxim Tsunamis.
I have used them on occasions when nothing else would do, as they are just too expensive.
I will keep that in mind and thanks. The WISP business is very new to me as I had a network dumped in my lap literally overnight due to the sudden death of the prior admin.
My only prior experience was with BreezeComs and Deliberants- everything bridged. The RB133+Sr9 looked like a very cost effective 900Mhz CPE solution. The network is currently flat-collisions rampant- so MT routing at several APs will be added. The learning curve is rather steep, so I appreciate the feedback on this forum. It proves that if you ask a stupid question you don’t always get a stupid answer.
I will have a new AP soon with nothing but MT/Atheros and have been reading every post on the deauth/reconnect problems. I will be starting at 1 client and building to 30 so I may be able to shed some light on that problem-or at least post the results. Thanks again.
Well-still hammering away on my test setup with no luck getting pings through.
2- RB133c/SR9 units
One WLAN in Bridge mode, the other in Station mode
I’ve created an EoIP interface on each unit with MACs of 00:00:FE:00:00:01 and :02
I created a Bridge on each and added ether1 and the EoIP in ports.
Interfaces are all running.
The radios see each other fine with a -34 signal, they are registering, SNR>60, RX/TX packets are going through.
The ether1 IP addresses are 192.168.1.101 and 192.168.0.102
The wlan1 IP addresses are 10.10.1.0 and 10.10.2.0
Pinging any IP address on the other unit results in a “no route to host” or timeout.
Something is missing-any idea what it might be?
Thank you Louis.
I thought I should be using WDS instead of EoIP and I’m sure it will work correctly once I reconfig the 2 units in WDS mode. I’m still curious why I can’t get a ping across using an EoIP tunnel bridged to ether1 on both units, even though it might be a less efficient way of doing it. The current config has a destination address of the other unit’s wlan for the EoIP tunnel, and vice versa.
WDS implementation worked fine. I can ping both wlan1 and ether1 from the remote unit.
My next question is in a typical wireless client setup, is it necessary to create a WDS bridge, or can ether1 and wlan1 simply be bridged in order for the client computer to connect transparently to the AP?
