Rob,
1.The helper address will do the job for you.
2.It will actually forward other default udp ports.
You can block these if you wish using the command.
no ip forward-protocol udp 37
no ip forward-protocol udp 49
no ip forward-protocol udp 53
no ip forward-protocol udp 67
no ip forward-protocol udp 68
no ip forward-protocol udp 137
no ip forward-protocol udp 138
3.The following config is redundant for this
requirement.
access-list 150 per udp any any eq mobile-ip
!
interface ATM1/0
ip directed broadast 150
regards
farid
