Invalid udp relay pkt from interface vlanxxx

Hi,

I am trying to configure a Powerconnect N3024 switch with the ip helper-address option.

My configuration is at the end of this post.

The problem is that I already did this exact same configuration on another N3024 in another site and it works.

this is the error I am getting now <187> Sep 24 10:30:48 192.168.8.2-1 IP_HELPER[122459668]: relay_main.c(576) 558 %% Received an invalid udp relay pkt from interface Vl220 Src ip 0.0.0.0: Src port 68 Dst ip 0.0.0.0: Dst port67 len 300

I really need to figure out the problem.

my current switch is at firmware 6.1.1.7 and the one I did before is at firmware 6.1.0.6 so I will try to downgrade this switch and see what happens.

Thanks in advance.

Just to add to my post. After downgrading to firmware 6.1.0.6, the errors have gone away and the IP Helper is working. Maybe this will help others...

Hi,

The new firmware version (6.1.2.4) should fix this issue.
