Two Internet lines to improve speed

RouterOS Beginner Basics
1

Hi community,

Currently I’m running a PPPOE-out1 VDSL2 connection to my ISP and my homenet behind the router.
Due to speed issues (650meters away from the ARU) it is not possible to get more than 35mbit.

Following idea.
Take from a second provider which is available (cable modem ISP 50mbit+) a connection and configure it as load balancing.
But I can’t move completely to this cable provider as he uses CGN and my installation would not be reachable from outside.

Question:
Is it possible to configure both lines active and balancing the traffic out?
But the home is only reachable from outside through line1 (VDSL2 with dynamic official ip? - via the DDNS Mikrotik service)
How will my company’s VPN from my employer react if I connect via 2 different external ip’s?

What do you think?
Makes sense in my situation or total bullshit?

Thanks in advance,
Christian

Hi

It’s doable: if you have multiple connections going out, these could be spread over the two links.
If you want to be reachable from outside, you would need to setup destination nat rules on the VDSL interface.
Wrt VPN, I’m guessing you’ll have a single vpn session active. If it can support mobile users, then I don’t foresee any issues.

With two links, a single connection will not be faster. More will load both links.

Hi,

Thanks for your answer.

What do I need to configure to get both external links loadbalanced and utilized?

Kind regards, Christian

You have few options, depending on preference / needs.
