Hello, I successfully set up a tunnel with tinc using the tun interface. however I need a tap device, because I need to run the OLSR routing protocol on the tunnel and if I use the tun mode OLSR will just skip the interface. (It is a well known thing, I had this issue before also when using OpenVPN in the past). The problem is that I cannot make tinc use a tap device. I created the tap0 interface with tunctl, however I have no...

...of me, but I think the prio qdisc doesn''t work as advertised in any document I could lay my hands on. The following tests and observations were made with Linux kernel 2.6.20.21. This makes it up-to-date in the 2.6.20.x kernel family. My problem was that the link quality reported by the olsr.org olsrd degraded depending on the amount of payload traffic was transferred through an adhoc/mesh interface. The LQ is calculated from the packet loss of LQ Hello packets sent through this interface. To make sure normal traffic does not interfere with this value, olsrd sets the TOS field to 0x...

...erly) Theroy says that using 2 interfaces on different channels and ensuring that data recieved from one interface is forwerded on another will increace perfornamce. I did not observe the same. I found the performance reducing by 1.5 times when this static rule based routing is compared against OLSR Protocol. I used iperf for measurements. Both TCP and UDP performance was low. Please let me know your views on this. Is rule and multiple table lookup very time consuming ?
