Checking the basics.. You got a firewall right? It's on? Ports closed?

Negative - that's why I was thinking of giving Portmaster another go but am open to any solution like that.
Yes the PC will be unattended for many hours at a time.
I'd just install UFW and either set the default for incoming and outgoing to deny and unblock the game ports manually, or just set incoming to deny and outgoing to allow.
You could pair that with OpenSnitch to see all attempted incoming and outgoing connections and block them by default, and then just allow the ones you want as they happen.
Thank you for these suggestions! I've been looking for something like Opensnitch for a long time.
Unattended? I'd use a bios password and disk encryption
You might find it helpful to look up "Evil Maid Attack" as you will be susceptible to that.
I guess if you want to be paranoid you could get a new hard drive and install just what you want for the LAN and keep personal info off it. Then just swap back when you get home.
I recommend gumming up the USB ports with chewing gum, and then wrapping the whole under case in a condom with airholes. Finally, lather any exposed peripherals with butter and marmalade, and walk by occasionally to just make intense eye contact and fart.
If that doesn't work, I don't know what will.

Update your bios, grab a clean disk image before you go, nuke it from orbit when you get back and restore from backup.
Make sure your BIOS is up to date
Install Fail2Ban, maybe?
Don't know anything recent, but years ago they began blocking network traffic between rows. That killed what little self hosted LAN play was still happening but kept stuff from spreading across the whole BYOC.
Don't go, it's a trap
