I need some assistance to hopefully stop banging my head against the wall.
I am trying to get a qBittorent App/ hosted in TrueNAS Scale 25.10, assigned assigned to the 192.168.3.0/24 subnet and VLAN 1337. This is from my main network on 192.168.1.1/24. I plan to restrict inter VLAAN communication later, but focused on the gateway issue.
I’m struggling to figure out what I am doing wrong. I even created an alias that includes the VLAN 1337 Device(s), as well tagging the traffic to allow a floating rule to stop this traffic from exiting on the WAN.
Unfortunately, when downloading a Linux Distro ISO as a test, the data appears to still be traversing the WAN. Am I the embodiment of Layer-8 issues..? Am i missing something stupid?
Custom IP addresses for apps currently work for ingress only. Any egress traffic will just use the TrueNAS host primary connection (the one with the default gateway).
The TrueNAS control plane (UI, API), the sharing services, and the apps all use the same IP stack, so this is expected.
If you must have true separation, create e.g. a VLAN without an IP address for the NAS host, create a bridge on top of that VLAN. Then create a VM connected to that bridge. VMs are the only entities that can be completely isolated from the host networking today.
