forwarding broadcast-wol

For wol development I need to forwarding broadcast. The configuration is:

The wol server is in vlan 50. The stations are in vlan 50

!

ip forward-protocol udp 12287

!

interface Vlan50

ip address xxx.xxx.xxx.xxx

no ip redirects

ip directed-broadcast 101

no ip proxy-arp

!

The problem is that I see in the switch where there are the workstations, a broadcast that have the origen mac-address in vlan 52. The switch know this vlan, so, the stations in vlan 50 don't receive the brodacast.

Can somebody help me with an idea?

Thanks.

Marcelo

Are you trying to know why you can't get broadcast from VLAN 50 in VLAN 52?

If so, VLANs divide broadcast domains.

Marcelo,

You need to use the ip helper-adress command in conjunction with the ip forward-protocol command to take the broadcast packet from one Vlan to another in form of unicast.

I'm not sure if it will work for Wake-On Lan packets but it's worth a try.
