Hi Everyone,
I have a routing situation where Tinc looks like it could come in extremely
useful, but I have a query I hope someone can cast an eye on, as I'm unsure
whether Tinc can help me here.
I currently have a Quagga OSPF linux router which connects LAN A to LAN B over
the quickest available of two routes (both routes at both ends connect to Quagga
boxes to prevent collisions).
One of the routes involves connecting over a wireless bridge (which can't be
set to routed mode) and the other connects over a routed wireless connection.
i.e.
LAN A OSPF --- W/less (NOIP) --- Wireless (NOIP) --- LAN B OSPF
+-- W/less 1.1.1.1 --- W/less 1.1.1.2 --+
This is basically to allow redundancy of the NOIP wireless, which drops at the
first hint of fog or mist. :-)
Is it possible to configure Tinc to connect over one of two possible routes like
this?
And if so, is it also possible over a bridged connection which has no external
IP address (by specifying the interface in the config file)?
I realise there are other ways to do this, but I'm hoping that my previous
post regarding Tincs ability to hop across VPNs will allow the site at the end
of the Wireless to connect to other external VPNs.
If you've had the patience to read this far, then thanks for any advice you
can offer!
John

But a wireless bridge doesn't mean you don't have those addresses on both sides.> I realise there are other ways to do this, but I'm hoping that my > previous post regarding Tincs ability to hop across VPNs will allow > the site at the end of the Wireless to connect to other external VPNs.That will work.> If you've had the patience to read this far, then thanks for any > advice you can offer!It should be possible to do what you want with tinc, so go ahead and try to set it up, if you run into problems feel free to ask for more help! -- Met vriendelijke groet / with kind regards, Guus Sliepen <guus@sliepen.eu.org> -------------- next part -------------- A non-text attachment was scrubbed...

I think what might be more elgant here is to setup Tinc as a bridge for my routed wireless, and use STP at either end to prevent collisions (one end on the switch connecting to Tinc and the other on two linux boxes). LAN A --- STP Switch --- W/less (NOIP) -*- Wireless (NOIP) --- Linux STP Bridge --- LAN B *plus* LAN A --- STP Switch --- Tinc Bridge -*- Tinc Bridge (with STP) --- LAN B This should hopefully make use of Tincs Bridging function to bring LAN A and B into the same subnet, give a failover in case one of the connections dies, and also give LAN B a Tinc server to handle connections out to other places. Quite looking forward to having a go at this. Thanks again for your help, Guus.
