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, 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.
