FortiSwitch F148 Standalone mode VLAN Managment access problem

[marcin_iwa]

Hi,

i have problem with correct settings for VLAN mangment.

I have two subnets

LAN (192.168.0.0/24) VLAN1 (connected to D-LINK Switch)

MGM (10.10.5.1) VLAN5 (FortiSwitch)

Two switches are connected to my Firewall SonicWall on separete port (PORT0 for D-LINK, PORT4 for FortiSwitch tagged 5)

Fortiswitch is connect to my firewall on port 23 (native VLAN 1, Allowed VLAN 5)

I Create VLAN interface on Firewall and set access rules for allow all traffic (temporary) between VLAN 1 and 5

On Fortiswitch i connect two devices on port 7,25 (Native VLAN5, Allowed VLAN 5)

Communication work, i can access from LAN to MGM via ping and https and vice versa, devices inside VLAN5 also have communication beetwen each otcher.

Problem is when i try connect from LAN to FortiSwitch to managment access. I can't any ping or HTTPS.

In FortiSwitch i create VLAN5-MGM with ID 5 with ip 10.10.5.1/24 and access HTTPS,PING,SSH as physical interface select only one available internal (on System-> Network->Interface->VLAN)

On Switch->Interfaces -> internal have native VLAN 1 and Allowed VLAN 5

When i try to connect to switch from VLAN 5 (i connect to port 7 on the switch) is ok, i can access via ping, https, ssh, but not from LAN.

How i must set up switch / VLANS to connect to switch managment from LAN ?

On Router->Config->Static set up route to 0.0.0.0 0.0.0.0 via device VLAN5-MGM Gateway 10.10.5.1

Thank you in advance for your advice.
