Also double check your installed _updown.mast. You will see this:

         # note "fwmarkmask" is an (obsolete) Openswan patch to "ip" command.
         # note2: iproute2-2.6.22-070710 supports mask via /mask notation instead
         # ip rule add fwmark 0x80000000 fwmarkmask 0x80000000 table 50
         ip rule add fwmark 0x80000000/0x80000000 table 50
         ip route add dev $PLUTO_INTERFACE table 50

For the 2.6.23 version you need to use the line with "fwmarkmask". With
2.6.32 you need to use the line with 0x80000000/0x80000000.
