VPN Tunnel issue with Secondary ISP

Ninja11 — Sat, 24 Jul 2021 19:01:38 GMT

Hi Guys,

I have created a IPSec tunnel using secondary ISP on the gateway while we already have tunnels on the primary ISP.

The tunnel was created and it was working fine unless I noticed that it was still using the main ISP line.

Is it possible to create a IPSec tunnel on secondary ISP while primary is having tunnels.

What needs to be done in this case to use the secondary line?

Thanks for the reply.

I think if I go ahead with link selection it will cause other tunnels to shift from Primary to Secondary ISP line.

I want to keep existing tunnels on primary ISP and run this new tunnel on secondary ISP.

Is it possible to have active tunnels on both Primary and Secondary at the same time?

You may use route based vpn, 2 tunnel interfaces with static or dynamic routing for load balance, like OSPF over IPsec.
