Hi,
I'm having a issue with getting acces from vlan 11 to vlan 14
the DHCP server is on Vlan 11 and it is suppose to give IP addresses to devices on Vlan 12-14 but i can't get it to work.
Here it the config atm.
ip route 0.0.0.0 0.0.0.0 172.18.231.1
ip route 172.16.1.14 255.255.255.255 172.18.231.1
ip route 172.16.1.27 255.255.255.255 172.18.231.1
ip route 192.168.1.0 255.255.255.0 172.18.231.1

Is it just dhcp-relay that is not working, and have you tested the IP routing by configuring a client with a static IP and default gateway to verify that IP routing is working? Do clients get an IP address?
One thing that I found is that on vlan 11:
vlan 11 name "SHIP NET" untagged 1-34,36-44,47-52 tagged 45-46 ip address 172.18.231.254 255.255.255.0 ip helper-address 172.18.231.20
You have an ip helper-address in the same subnet. This should not be done, as the DHCP server should respond directly in that subnet, not via an IP-helper.
If it is indeed just a DHCP issue (and removing the helper from vlan 11 does not resolve your issue), you can check the statistics from the dhcp-relay:
If you have urgent issues, please contact your Aruba partner or Aruba TAC (click for contact details).
