<DIV><FONT face=Arial color=#000000 size=2>Hi, I have the following setup. Two
linux systems with two [test] external interfaces encrypted with ipsec
[transport].</FONT></DIV>
<DIV><FONT face=Arial size=2>Two gre tunnels that pass 10.200.0.0/24 and
10.200.1.0/24 network traffic.</FONT></DIV>
<DIV><FONT face=Arial size=2>Testing the balanced tunnels I would setup iptraf
on one and ping from the other. The results would be as expected; traffic would
be split between the two interfaces.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Testing with an ftp transfer of 300MB I would get
various results:</FONT></DIV>
<DIV><FONT face=Arial size=2>1. one interface would be transfering at 36Mbit/s
the other would be at 1.5Mbits/s [a -> b]</FONT></DIV>
<DIV><FONT face=Arial size=2> or one interface would be
transfering at 29Mbit/s and the other a 0.</FONT></DIV>
<DIV><FONT face=Arial size=2>2. I would get the same results from
[b->a]</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is there something I missed or did not configure
properly? Any help or suggestions would be appreciated.</FONT></DIV>
