Hello,
Due to AP300 EOL it is required to update customer's exising FW on the RFS to support all existing AP300 both AP650 for future growing. Stable running configuriation besed on build 4.2.0 using ip-helper, relays DHCP requests to the server outside vlans. When migrating to 4.4.1 an old confuguration fits correctly, but DHCP relay stop working. All dedicated network infrastructure and its configurations remains the same. Any suggestions whats wrong with ip-helper during FW upgrade?

Thank's to all, solved.
To remember when enabling ip-helpers:
1) IP-pool on the DHCP server must be described for each remote subnet
2) Route between the DHCP server and the subnet we want DHCP relay work must exist
3) DHCP Relay to be enabled on RFS.
On my case after fw upgade the route to DHPC server lost due to 3rd party network infrastrucure issues.
Without looking at the running-config its going to be hard to determine whats going on. Regards, Kevin
