DHCP IP address not renewed automatically on WAN Interface - 300D

Hi all,

 

Recently we configured new WAN link on our FortiGate 300D  firewall. WAN interface configured as DHCP mode and it received IP address initially. From ISP end they are using Huawei fibre modem to connect FortiGate firewall.

 

After the DHCP lease expired, it's not renewed and lose IP address as well. we tried to change multiple settings but no luck. FortiGate 300D firmware 5.4.3. attached dhcp logs as well

 

ISP modem (Bridge Mode) ==> FGT WAN interface ==> LAN

 

If anyone have same problem / solution please share with us.

 

Regards,

Sivaguru D
