RE: ip directed broadcast with ACL

I would configure both:

1)In order be able to forward this traffic

ip forward-protocol udp mobile-ip

2) In order to actually forward the traffic

ip directed-broadcast 101
access-list 101 permit udp any any eq mobile-udp

The question is where should we configure this ?

R1====R2====R3

Imagine R1 as the Broadcast source. So we would need to configure 1) in R2
and 2) in R2's interface facing R3.

Unfortunately i don't see an easy way to test this. Tried NTP Broadcast and
RIPv1 but they both have TTL=1.

Wait, maybe IP SLA... I will try it now.

If I were to forward mobile ip with the ip helper.

I could do both of these correct. This is doing the exact same thing,
right?

ip forward-protocol udp mobile-ip

OR Do:

 ip directed broadcast 101
permit udp any any eq mobile-ip

It does not look like using the ACL, and permitting mobile IP only, disables
the forwarding of the ip-helper default protocols. This right?
