Hello!
Scenario:I have a RFS6000 with several groups of AP650 in remote sites, separated by routers (L3 adoption, fixed IP at VLAN 1). External DHCP servers avaiable at RFS and remote sites. There's no DHCP service at RFS. RFS and APs use public IPs (no NAT in anywhere). Firewall with default settings. WiNG 5.2.3.
With ''Tunnel'
Bridging Mode at WLAN, everything works great and the traffic flows by the network on the RFS site. Clients get IP on the DHCP server at RFS site.
Problem:I need clients using the remote network (at AP site), not centralized by RFS, with clients getting IP by DHCP servers at the AP site/network.
I changed
Bridging Mode to 'Local', and set
DHCP Relay IP Address to desired DHCP server IP on each AP (IP helper), but clients don't receive an IP. If I set an local IP address manualy, it's works.
If I check 'Respond to DHCP Relay Packets', get 'Unknown Error: Both, dhcp-relay-incoming and ip-helper-address, are configured on interface vlan1.'
Example AP VLAN setting:
#show context
interface vlan1
ip address x.x.x.x/x
no ip dhcp client request options all
ip helper-address x.x.y.y
no ip nat
no dhcp-relay-incoming
What can I do to my clients get their IP by DHCP serve at the AP local site/network? Need more to forward DHCP? What I miss?
