The story:
We need to create two separate VLANs for Office and Service-center. We have Procurve 4204vl switch. Office-VLAN (192.168.10.0/24) contains DNS, DHCP, NAS and GW for internet access. Service-VLAN (192.168.11.0/24) will have a lot of incoming PCs. Computers from Service-VLAN must not see computers from Office-VLAN.
Primary task:
Computers from Service-VLAN should be able to receive IP configuration from DHCP (192.168.10.7) and have access to internet through GW (192.168.10.99).
Secondary task:
Computers from Service-VLAN should be able to access files on NAS (192.168.10.3).
I've created two VLANs. Configured two scopes on DHSP server (192.168.10.0/24 and 192.168.11.0/24). Enabled "ip routing" and "dhcp-relay" on switch. Added ip helper-address in Service-VLAN pointing to DHCP (192.168.10.7).
The problem - clients in Service-VLAN do not receive configuration from DHCP server.
Please see attached image and config for refence.
Please advise.
Solved! Go to Solution.

Re: DHCP-relay problem with 2 VLANs

Thanks!
