Hi, I have the following setup. Two linux systems with two
[test] external interfaces encrypted with ipsec [transport].
Two gre tunnels that pass 10.200.0.0/24 and
10.200.1.0/24 network traffic.
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.
Testing with an ftp transfer of 300MB I would get
various results:
1. one interface would be transfering at 36Mbit/s
the other would be at 1.5Mbits/s [a -> b]
or one interface would be
transfering at 29Mbit/s and the other a 0.
2. I would get the same results from
[b->a]
Is there something I missed or did not configure
properly? Any help or suggestions would be appreciated.
