WOL Access list

[dmesser-hhs]

Ok so I have my WOL server successfully waking up clients across many VLANS and even across a Firewalled MPLS connection.

My config to pull this off was

#Global

ip udp-bcast-forward

ip directed-broadcast

#VLAN 1 - this is where the server lives no configuration on this VLAN. (The application uses UDP port 7)

#VLAN2

ip address 172.20.1.1 255.255.255.0

ip forward-protocol udp 172.20.1.255 7

#VLAN3

ip address 172.18.6.1 255.255.254

ip forward-protocol upd 172.18.7.255 7

Like I said now everything is working great.  But I want to protect myself so that only this server can send broadcasts to these vlans. My question is should I create an access list so that only UDP port 7 from my server?  The way I have the config now I am thinking that only UDP 7 will broadcast to the configured VLANS.

I just want to make sure that for some reason I'm not allowing all broadcasts to these vlans and create unneeded traffic. Do anyone have any suggestions on whether or not to create an access list to restrict this traffic? (Without breaking anything) LOL

Thanks for any help!
