Well, I did as you suggested and while it helps a bit, I still get
random hangs on a tcp connection. For example I use a source control
management program called perforce and under large synchronizations it
will just stop after about 30 files. I kill the sync and start it up
again and it picks up where it left of and gets a bit farther before
hanging again.
Kind of annoying. Looks like Cisco didn't really test this one.

Your MTU should stay at 1500 for the primary eth0 device. I had the
same issues that you are seeing (btw I ment 1359 sry) for some weird
reason under the 2.6 kernel the mtu automagicly drops. Once you bump
your mtu back to 1500 when the vpnclient is active you will return to
'normal' operation.

Actually for me the MTU is changed to 1359 which is the same value on
the VPN client running on FC1 with no problems.

Could you explain this a bit more?
I downloaded the 4.0.4a client and it builds and start for me on
fedora core 2 test 3, but it freezes up a strange times (large
listings from 'ls -l' or large amounts of output from a compile).
Would this MTU setting cause that? What should the MTU be?
On another note, has anyone noticed that the DNS lookup is strange
with this client. Sometimes host lookup is fast, sometimes it takes
long time. Perhaps the MTU problem again?

On the Cisco client be sure to fix the MTU after you bring up the
vpnclient connect command. For some reason it changes the ETH0 MTU
to 1389...

I have searched high and low for a way to get the cisco vpn linux
version 4.0.3.Bk9 client to work with a 2.6.5 kernel.
I have tried the deadlock patch from www.anomalistic.org but it
doesn't work for me.
It worked great using a 2.4 kernel.
Does anyone have any other ideas?
Looks like vpnclient-linux-4.0.4.A-k9.tar.gz supports 2.6.
From the readme (which I had to submit a blood sample, retina
scan, and
sign away my first born for) :
