Tailscale and Multi-WAN


Is there a way to route Tailscale traffic over a secondary WAN connection? Has anyone done this and can point me into the right direction?

I have tried setting a different gateway group in firewall rules and also playing with static routes, but haven’t solved this yet.

If there is an easy way to set a different gateway, it would be great. Because of my limited upload speed, I got a second WAN connection for offsite backups. Site-to-Site VPN with Tailscale is easy to set up and the router on the remote site only supports outdated/slow IPsec algorithms, so Tailscale would be preferred, but the traffic would need to go over the second WAN connection.
