R: [leaf-user] Wrap and openvpn with TLS. PLZ HELP me!
I think you have right!! After some minutes(!) and a lot of failing handshakes, connection was established! The problems is now performance. I need a crypto tunnel with a speed higher than 14.400 Mbits/s end not 5-6 Mbits/s (max I achieved). Probably this can be obtained with an HW crypto engine, but at this point costs are similar to a custom pentium celeron PC. Do you know some other alternatives??

I am surprised it takes so much time, I am building IPSEC tunnels all the time with the WRAP board (using a derivative of Bering 1.2) and never have delays. I would check the handshake and see if you have packet loss. Else it may be possible that the crypto stuff used by openvpn is not as well suited as the IPSEC implementation. Using AES should allow you to come close to 100Mb I believe the crypto board is around USD 100.- I never tested it, my tunnels go through the internet, so I never have sufficient bandwidth to saturate the WRAP. cheers Erich THINK Püntenstrasse 39 8143 Stallikon mailto:[EMAIL PROTECTED] PGP Fingerprint: BC9A 25BC 3954 3BC8 C024 8D8A B7D4 FF9D 05B8 0A16 --- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?

> M why does it fail? > > should allow you to come close to 100Mb > 100Mb??? I connected wrap to a celeron pc with a cross cable. Then I set up these boards as routers for two different nets. Here is what i obtain with a ftp tarnsfer between two pc conncted to this routers: A = pc behind wrap B = pc behind celeron Putting a file (100Mb) from A to B (i.e. traffic flow A->B) 540 Kbytes/sec with TLS tunnel, 926 Kbytes/sec with a tunnel without encryption, 6300 Kbytes/sec (50Mbits/sec )with "route only" (no tunnel). Getting the same file from A to B (i.e. traffic flow B->A) 825 Kbytes/sec with TLS tunnel, 1700 Kbytes/sec with tunnel without encription, 6200 Kbytes/sec pure routing. The differences between putting and getting are probably(?) due to the fact that encrypting is harder than decrypting, so celeron works better than geode. Exchanging wrap board with a P4 do the same work in 8500Kbytes/sec10900Kbytes/sec10900Kbytes/sec (put) and 4300Kbytes/sec10900Kbytes/sec10900Kbytes/sec (get) An epia (Sis550) test board is slower than wrap, but there are no problems in TLS negotiation.

The routing capabilities of both machines in routing only set up are comparable, e.g. the ipstack behaves in a comparable way. I doubt the computing capacity of the Geode would be that low though. There must be some overhead elsewhere.
