Comment on Weird (to me) networking issue - can you help?

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 submitting, 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.

I don’t think I quite explained the situation well enough: my server only has 1 ethernet port (same as my PC), otherwise I wouldn’t have bothered with vlans (well, I would still have bothered, since my house still only has one “backbone” cable running through it, but I would have configured it on the switches only).
Anyway… a few of the things you say/imply go against my understanding of networking, so one of us would better go back RTFM as you suggest :) (just kidding - most probably I just don’t understand what you mean)
