I tested nated vista client (l2tp/ipsec) with openswan server (xl2tpd and openswan 2.4.9 or xl2tpd and netkey) and MS WIN 2k3 RAS server. In my test environment is NAT linux box with kernel 2.6.22.x. Vista client disconnets when rekeying begins (after one hour or 250MB), nonnated vista client works fine. Nated vista breaks tunnel only with linux server not with MS WIN 2k3 RAS server. On some rare ocasions vista client succesfully rekeys (2, 3 times at most).
