DHCP Relay on external interface 3030 concentrator

I have a problem using the DHCP relay function. The DHCP server is in the internal network. In the log data of the concentrator i see the DHCP request, at the DHCP server i see the assigned IP address but the client never get the answer. At the concentrator i can´t see any DHCP reply. We have checked the DHCP function between client and server directly connected ... no problem. So it seems to be a problem with the concentrator not forwarding the DHCP reply ....

Filter for internal interface is Any-IN/Any-Out, for external interface i have added the DHCP filter. I know the documentation:

Any hints

See bug CSCea64707: DHCPRelay fails if enable management-access inside. The bug was first found in 6.3(1) and First Fixed-in Version 6.3(2), 6.3(1.100). Hope that helps.

Re: DHCP Relay on external interface 3030 concentrator

Thanks for the answer, but the bug isn´t solved in any version or at any interface. I have tested it with several version and interface combinations ....

We will use a DHCP server ..
