Need help combining xDSL + LTE with loadbalancing

Aloah crossfire!

For everything else except for gaming my internet is total garbage and it's time to step up and upgrade my connection. Therefore I am looking to combine the internet connections of my xDSL Modem and a LTE Modem, which I'm going to purchase soon.

My situation right now is that I share my internet togheter with my girlfriend, who often watches her university lectures per stream as well as vlogs. At 6mbit/s download and 200kbit/s upload it always ends up in a total mess.
The modem is connected to a port switch, and 4 devices (TV, Laptop, PC, PS4) are connected by LAN, while a printer is connected per WLAN directly to the modem.

Basically I would like to use the DSL connection for gaming on my PC only, while using the LTE for everything else,
so that my gf's laptop doesn't connect with the DSL at all. All the applications on my PC should run by LTE while I play, let's say CS:GO for instance simultaneously on the DSL connection.

Now where you guys come into play is helping me out with the requirements needed and how to setup all of this properly.

I am very grateful for any advices and also willed to pay something if someone is eager to help and spend time on it
actually getting it to work properly!

You can use PfSense for this: https://doc.pfsense.org/index.php/Multi-WAN
Connect both modems to the Pfsense router, set-up dual wan and make rules for traffic that you want to use for a specific connection. If would advise you to use the Pfsense forums if you can't figure it out, it's a helpful community.

Only downside, you will need some hardware, but for those connections you can run PfSense on low-end hardware, you just need to have at least 3 network connections, or use vlans(but that will make it a lot more complicated) PfSense can also be used as a virtual machine, if you want to test it.

Another option perhaps is something like the Draytek Dual WAN router https://www.draytek.com/en/products/router/broadband/ but I don't have experience with that. Some consumer routers can also do Dual WAN, but don't have the options to define traffic.

Another option is https://www.ubnt.com/products/#routing like the Edgerouter Lite, but you will need to configure most things like this https://help.ubnt.com/hc/en-us/articles/205145990-EdgeMAX-Dual-WAN-Load-Balance-Feature

I can understand your frustration. I have a virtual Pfsense router at home with a 500Mbit fiber optic connection image: 5705901711

I also have pfblocker package installed https://doc.pfsense.org/index.php/Pfblocke You can block IP's (Poland) with this and use the DNSBL feature to block ads with DNS.

Thanks for the detailed reply! When using a hardware load balancer, is it even possible to attack certain applications to a certain connection?
Parent
attach, yes based on port with NAT. So to set this up you would need to know the ports used in CS:GO and define rules for that so that when you play CS:GO only the DSL is used for example.
Parent
Yes attach :D Sounds good, but aren't csgo ports always also related to the server's configuration? Except for the ones using standard ports of course

https://doc.pfsense.org/index.php/What_is_policy_routing
Look for this on pfsense forum and look in the Multi-WAN section and you will get more answers. You will need a firewall rule to match CS:GO traffic it should work with destination port or outbound port. There is just a lot of configuration necessary and sometime adjusting it to make it work like you want. With pfsense you an adjust the firewall rules with no downtime.

Pfsense also have aliases that you can use in your firewall rules
for example make an alias with (ports for DSL connection for example) and you can just add all ports that will be used on the DSL line and reference that alias in a firewall rule, than you only need to have one rule instead of 50 and if you want to make adjustments just change the alias.

i kinda hate the new UI

It's reponsive design, you can use pfsense now on your phone. But also on wide screens you can have more graphs and stuff on the dashboard and more graphs are better.
Parent
Graphs is the most important thing in network engineering
Graphs are heaven.
