VLAN Switch on 100f not giving out native IP address on trunk

[JoseVold]

Hello everyone,

Looking for a solution to this after a week of searching and trying.

I wanted to setup a FG 100F v7.0.15  to be a vlan switch. I removed all the ports from the switch except port1 as it will not allow me to remove the last port of course. Problem... after setting up all the vlan switch vlans and adding the ports I want to the vlans, I create the trunk. 

The trunk will not hand out the IP address from native vlan 1 or 0 on this product. To test my work before adding to the network, I take the PC and tag the NIC with the corresponding VLAN and I get the correct IPs per VLAN. If I remove all tags on the NIC leavin the NIC on 0 (Untagged) I get nothing when I am expecting the native VLAN 1 IP addressing.

What gives here?

FGT's VLAN switch "trunk" port is NOT a general trunk port you're familiar with.
It (ASIC) is not designed to do what you're thinking it "should" do. It would just aggregate ONLY those native VLANs configured on VLAN switch interfaces I showed above.

FG100F is one of the most popular models in the series. So probably the model wouldn't matter to choose FortiOS.
It's up to what applications of the FW you use. But 7.6.x is still very new and most people who are looking for stability would avoid. 7.4.6 is getting closer to be really "mature" but still waiting for many bug fixes like below:
https://docs.fortinet.com/document/fortimanager/7.4.6/release-notes/454729/known-issues
7.2.11 is expected to be released next week, which includes a couple of HA related bug fixes I've been waiting for. But otherwise, it's really mature. So this might be what you're looking for unless you need some new features released with 7.4.
