5820af-24xg: Wake on LAN
Hi everybody,
I want to forward WOL broadcasts destination port udp 7 with destination IP 255.255.255.255 to three vlans.
With ip forward-broadcast enabled, only WOL packets with the destination IP of the specific subnet (eg. 192.168.1.255) are forwarded, but not with destination IP 255.255.255.255. Anyway, broadcast pakets with udp destination port 7 are not forwarded at all, other udp ports are forwarded (???).
I also tested the udp-helper function for udp 7, and configured "udp-helper server 192.168.1.255" on the according vlan interface. No luck so far.
Has anybody successfully configured broadcast forwarding with udp 7 & IP 255.255.255.255?
TIA,
Stef

Hi,
This is what I had saved in my notes:
Comware configuration
# Global enable ip directed broadcast forwarding:
ip forward-broadcast
#
# Interface of transmitted WOL (WOL tool) packet
interface Vlan-interface11
ip address 10.0.11.1 255.255.255.0
# Interface of device to be woken, requires interface directed broadcast
interface Vlan-interface12
ip address 10.0.12.1 255.255.255.0
ip forward-broadcast
Next make sure to use the subnet broadcast address (in this case that would be 10.0.12.255) in the WOL tool.
See attached doc for sample,
Hope this helps,
Best regards,Peter

Re: 5820af-24xg: Wake on LAN
Hi Peter,
thanks for your reply.
There are two WOL servers in my network.
Server 1 (software management) generates magic packets with directed broadcast. I have already configured ip forward-broadcast, and it works fine.
But server 2 (ras) generates magic packets with broadcast 255.255.255.255. I did a lot of testing and configuration, but I had no luck with forwarding these packets.
Seems I have to find a way that server 2 also gererates magic packets with directed broadcast.
Cheers,
Stef

Hi,
Did you ever find a solution to this? I have this issue too.
