I tried setting mssfix at different values in the client and server configs
with no change.

I did do some packet captures and the problem does happen after a long
packet. I changed the MTU of the TUN interface with no change.

The firewall and openvpn are being done on a RHEL6 box. I do not see any
firewall that would selectively affect these packets and the packets do get
seen by both sides. I don't really have a good enough grasp of the issue to
recognize the problem though.
