IPv6 with Prefix Delegation on Fortigate. To use FortiSwitch CLI commands to check the FortiSwitch configuration: Verify that the switch system time matches the time on the FortiGate: get system status. Temporary work around for those would include to disable and reenable the relays, delete the relays and create it and as a last resort, we would create the DHCP pool locally.Ī VPN Account (Contractor) will be created to access the nodes that are being affected and we will be providing guidance if any questions arise.Ģ- Make recommendations to address problemģ- Provide suggestions that would aid us in not experiencing this in the future. The problem im facing is that eventough the DHCP Server sends the prefix delegation option to the client the. The issue that we're encountering is that at random times, the DHCP Relays Counter stop counting, multiples requests are being sent but not replies are given even though the relays IP are reachable. Our Edge Firewall is a FortiGate 3400E and our Site LSWs are Mikrotik 328-24P-CRS+RM.Įach Individual Broadband sites are pointing to 2 DHCP Relays IP (One for Traffic (VID163) and One for Management (1303)). In such cases, it is suggested to configure 'set allow-subnet-overlap'. As in the above case, since it was received via DHCP, FortiGate configured it on wan1 but only one route showed up in the routing table as connected.

We are a Telecommunications Company from Belize () and our main infrastructure is built around FortiGate & MikroTik Devices. FortiGate does not allow having to the same subnet on different interfaces with default config.
