Need help with vlan setup netgear xs728T prosafe

Need help setting up vlans on 2 netgear switches. Here is my setup.

 

Fortigate firewall port 24 is connected to port 27 on netgear xs728t

The interface "lan" on firewall has sub-interfaces with vlan x's

 

Port 9 on netgear xs728t is connected to port 10 on gs110emx

 

Questions:

How to pass/setup default vlan 1 and vlan 5 from port 27 on netgear xs278t to port 9 on same switch(xs728t)?

Also how to setup vlan on gs110emx so that vlan 5 is on port 1?

How to pass vlan5 DHCP to gs110emx on port 1?

How to pass vlan1 DHCP to gs110emx on other ports?

 

Below are pictures of configs for both switches

 

 

  • Solution:

    1. Starting with firewall, have interface "lan" setup with sub-interfaces with vlans (no change here)
    2. Netgear xs728t switch, created vlans and tagged ports 9 for both vlan1&5 and then tagged port 27 for vlan5
      1. port 27 is uplink to firewall
      2. port 9 is link to gs110emx switch(port 10)
    3. Netgear gs110emx switch, created vlans and tagged port 10 for both vlan1&5

    BTW: computer on port 1 on gs110emx is getting DHCP from firewall!!!

    If you need to transport multiple VLAN on a link (or a LAG): Create a TRUNK, make all VLANs TAGGED. This applies to the link where you connect the Fortigate, where you connect other switches. 

     

    Neither the XS728T nor the GS110EMX does DHCP. I assume you want to create access ports for the VLAN 1 resp. the VLAN5. So make these ports UNTAGGED and set the same PVID where you connect e.g. a workstation.
