openssh vpn tunnel and udp

Hi all,

I am using openssh 5.2 on fedora 11 to connect quickly two sites via tun.

It works like a charm with tcp but udp is troubling us. It looks like udp
packets with destination port > 8000 are being dropped. I disabled all
firewalling rules during tests, same result.

Any ideas what could be causing such behaviour?

thanks,
