RE: Slow transfer over cipe-tunnel

[Andreas Dahlén <andreas,AT,dahlen,DOT,ws>]

XP - FW   --   Internet   --   FW - XP
        1 Mbit         256 Kbit
  Athlon 1Ghz             Intel Celeeron 500

I think that the speed of the FW:s and the link is enough. I've tested
to minimise the services on the FW:s and made sure that there where no
 extra traffic over the FW:s.  Bur the transfer is still slow?

Shouldn't I get almost the same transfer rate of a FTP-transfer inside
the VPN as one FTP outside the VPN?

How could I check the UDP reply timeouts? Is there enything else I
could check? Some configuration options for Cipe?

I've testet Cipe 1.5.2 and 1.5.4 together with kerlnel 2.4.18 and
there is no difference.
