Sorry, other way around, 32666 and 220 works, but 0 doesn't.

0:      from all lookup local
101:    from 90.225.194.x lookup WAN1
102:    from 10.248.0.x lookup WAN2
103:    from 85.24.240.x lookup WAN3
121:    from all fwmark 0x100/0xf00 lookup WAN1
122:    from all fwmark 0x200/0xf00 lookup WAN2
123:    from all fwmark 0x300/0xf00 lookup WAN3
220:    from all lookup main
32766:  from all lookup main
32767:  from all lookup default
