OK. Built a test environment with openSUSE 11.2 and Factory using source
spoofing and had no UDP problems at all. So the three years old SuSE
patch seems to fix the problem too. SLES 10, which is used by the
reporter, was released earlier, so no wonder, that it fails. SLES 11 has
the patch and does not seem to be affected either.
