You have two NICs in a machine and two networks, one untagged and one tagged? This is a mess for a number of reasons. You have two routes and two adapters that don’t route to the default gateway of each subnet because you’re also tagging one portion of the VLAN traffic, and not tagging the other. That’s your problem.
How you’re going to fix it: learn about VLANs and subnetting, then let your router do the job it’s designed to do. You’ve already defeated the purpose of the VLANs by having them bridged with this one machine anyway. There’s literally no point except this confusing setup.
