Should Your Homelab Run Your Router?

Should Your Homelab Run Your Router?

TrojanHQ Answer: Big Fat No.

Let’s get this out of the way early.

Should your main homelab server also be your household router?

No.

Big fat no.

Do not do it.

Yes, it can be done.

Yes, some people do it.

Yes, someone on the internet will tell you it works perfectly because their Proxmox box has been running pfSense, OPNsense, Docker, Plex, game servers, Home Assistant, and eighteen experimental VMs for three years without a problem.

Good for them.

That does not make it good doctrine.

At TrojanHQ, the rule is simple:

The router is the front gate. Do not build the front gate inside the experimental lab.


1. Your Router Is Not Just Another Service

A router is not just another app.

It is not just another VM.

It is not just one more container in the stack.

Your router is the thing standing between your network and the outside world. It handles WAN, LAN, firewall rules, DHCP, DNS forwarding, VLANs, VPNs, port forwards, traffic control, and sometimes intrusion filtering.

When it dies, everything behind it suffers.

When it is misconfigured, everything behind it is exposed.

When it is rebooted for “just a quick update,” the whole house loses internet.

That makes it different from a media server, NAS, game server, AI box, or test machine.

The router is core infrastructure.

Treat it like core infrastructure.


2. Homelabs Are Supposed to Break

This is the part people forget.

A homelab is supposed to be touched, changed, upgraded, broken, rebuilt, tested, and improved.

That is the point.

You install things.
You remove things.
You pass hardware through to VMs.
You update kernels.
You test containers.
You swap drives.
You restart services.
You mess with bridges.
You experiment with firewall rules.
You try weird scripts at midnight because curiosity won.

That is homelab life.

But your household internet should not go down every time your lab has a learning moment.

If your main router lives inside your main experimental server, then every lab mistake becomes a network outage.

That is not smart.

That is fragile.


3. Virtualised Routers Are Powerful — But They Are Not Beginner-Safe

Virtualised firewall/router systems can be excellent.

pfSense and OPNsense are powerful. Running them under Proxmox or another hypervisor can work beautifully in the right environment.

But there is a difference between:

a dedicated firewall box running a router/firewall OS

and:

your all-purpose homelab server also running your main household router as one VM among many

The first can be good infrastructure.

The second can become a self-inflicted curse.

Virtualising your router adds extra layers:

hypervisor networking
virtual bridges
NIC passthrough
driver compatibility
boot order
VM startup order
firewall VM availability
host update risk
storage dependency
management access problems

If anything in that chain breaks, your internet can disappear.

And when the internet disappears, troubleshooting becomes more annoying because the thing you need to fix may also be the thing that gives you access to documentation, updates, remote management, and sanity.


4. The Reboot Problem

A normal router can sit there quietly for months.

A homelab server does not always get that luxury.

You might need to reboot it because:

kernel update
GPU driver update
Proxmox update
storage controller change
HBA troubleshooting
network card swap
BIOS change
RAM test
failed VM
Docker chaos
thermal maintenance
drive replacement
bad experiment

Now ask the real question:

Do you want every one of those events to kill your internet?

Because if the router lives inside that box, it probably will.

A homelab should be allowed to go offline without taking the whole house with it.


5. The “One Box Does Everything” Trap

One box doing everything feels efficient.

Until it is not.

The more roles you stack onto one machine, the more painful failure becomes.

If your NAS dies, storage is offline.

If your game server dies, players are annoyed.

If your AI box dies, rendering stops.

If your router dies, everything is offline.

Now combine them into one machine and you have created a single glorious point of failure.

That is not elegance.

That is a hostage situation.

TrojanHQ doctrine:

Convenience is not resilience.


6. Security Risk Goes Up When the Lab Touches the Edge

Your router/firewall is the edge of your network.

That is the last place you want unnecessary complexity.

A general homelab server may run all kinds of things:

web panels
Docker containers
test services
game servers
AI tools
dashboards
remote access tools
file shares
development environments
experimental scripts

Some of those may expose ports.

Some may have bugs.

Some may be misconfigured.

Some may be temporary experiments that accidentally become permanent.

Putting your router on the same general-purpose system increases the blast radius if something goes wrong.

Security doctrine should be boring:

router/firewall = simple, stable, isolated
homelab = flexible, experimental, replaceable

Do not mix the front gate with the workshop.


7. Power Use Is Not Always the Win People Think It Is

Some people argue that combining router and homelab saves power.

Maybe.

Sometimes.

But not always.

A router should usually be small, efficient, and always on.

A homelab server might have:

Xeons
Threadrippers
EPYC CPUs
HBAs
10GbE cards
GPUs
many drives
extra fans
cache drives
PCIe cards

That is not router-class hardware.

If your “router” needs a giant server running 24/7 just so the house has internet, you may have solved one problem by creating a bigger one.

The better doctrine is:

Use efficient hardware for always-on edge duties. Use powerful hardware for lab workloads.


8. The Better Setup

The sane setup is simple:

Modem / ONT
→ dedicated router/firewall
→ switch
→ homelab servers
→ NAS / VMs / game servers / AI boxes

Your router/firewall should be its own dedicated thing.

That can be:

a quality consumer router
a dedicated mini PC firewall box
a proper OPNsense/pfSense appliance
a low-power business router
a dedicated network appliance

Then your homelab sits behind it.

Now the lab can break without killing the house.

You can reboot Proxmox.

You can rebuild Docker.

You can swap GPUs.

You can mess with VLANs in the lab.

You can murder a VM by accident.

The internet still works.

That is the difference between a lab and a liability.


9. When Is It Acceptable?

There are exceptions.

If you are experienced, understand virtual networking deeply, have out-of-band access, have backup connectivity, have a spare router ready, and know exactly how to recover from failure, then a virtualised router can be part of a serious setup.

But that is not the average homelab beginner path.

And even then, TrojanHQ still prefers separation for the main household edge.

Experiment with virtual routers in the lab.

Do not make them the only front gate unless you are ready for the consequences.


10. TrojanHQ Rule

A homelab is allowed to break.

Your internet edge should not.

A NAS is storage infrastructure.

A router is network infrastructure.

A game server is service infrastructure.

An AI box is compute infrastructure.

They can work together, but they should not all become the same fragile point of failure.

The front gate should stay boring.

The lab can be wild behind it.

TrojanHQ doctrine:

Do not run your kingdom’s front gate from the same machine you use to experiment with dragons.


Final Word

Running your main router from your general homelab server sounds clever until the day it is not.

It adds complexity.

It increases failure impact.

It makes updates scarier.

It makes troubleshooting harder.

It can turn every server problem into a household network outage.

And for most people, the reward is not worth the risk.

Use a dedicated router or firewall appliance.

Put the homelab behind it.

Let the lab be powerful, messy, experimental, and glorious.

Let the router be boring, stable, and separate.

Because when the lab catches fire, the gate should still stand.

The Legion does not worship complexity.

It worships uptime.

And uptime begins at the edge.
