DHCP relay, SA520, SRW2420 and SG200-18

[luts_blits]

Hello,

First of all, sorry for my bad English. :-)

i've setup a little network with the following components:

SA520 ---trunk--- SRW2024 ---trunk--- SG200-18

                                 |                                   |

                     PCs, Servers,...                      PCs,...

multiple VLANS: Default: VLAN1  VLANs 10-15, 100 and 120

SA520 is configured as DHCP-Server for VLAN 11-13 and 15. For those 4 VLANs, DHCP works fine.

All Servers are in VLAN 10. Intervlanrouting is active on all VLANS except VLAN 15. DHCP-Relay for VLAN: 1, 10, 14 and 120 are configured with a Windows Server 2008R2 as DHCP-Server, in VLAN 10.

VLANs 1, 14 and 120 work fine when i configure a static IP, but not with DHCP.

I have tried Windows XP, Windows 7, Windows 8 on both Switches and in a VM and with a Mac, but i get no IP.

With Wireshark i tracet on the server and all clients but the only thing i see is a DHCP-Request on the client but non on the Server except VLAN 10.

I think the SA520 not putting throu the DHCP-Request from VLAN 1, 11-15 adn 120 to VLAN 10. Ist there an additional configuration needed?
