DHCP ERROR Cisco packet tracer

[danidiesel27]

I am currently encountering an issue with my DHCP server configuration and I was hoping someone could offer their expertise and help me resolve this problem.

I have attached my Packet Tracer configuration below for reference. If anyone could take a look and provide some insight, I would greatly appreciate it.

Thank you in advance for your assistance.

Routes are missing on GW router; in particular route to DHCP server. why?  OSPF routes are not being exchanged due to OSPF router id issue (process stuck in Exchange phase).   Both routers have same router ID for OSPF process, which is not ok (PT does not show error but it should).   you accidentally copy sub-interfaces from GW to FW creating OSPF issue.  Remove sub-interfaces from Fw router. save and reboot. OR add manually router id on FW and clear ip ospf process.  Then, FW router have no route to

172.16.x.x networks. you must advertise those into ospf process.

Also,

default gateway

of server "itself" is wrong; it should be next hop neighboring router.

Then I think

 ip helper

command is wrong as well. All sub-interfaces must have

 ip helper

command.
