    Hello everybody!

    I have two tailscale instances running, one at work, one at home. To access my internal lan from work I added a route to the box I'm running tailscale at work and use it as a gateway, the same goes for any pc at home that wants to access anything from work I add a route to my house's tailscale instance.
    When I use my notebook anywhere else from home or work, using a tailscale client I can connect to any PC from work but I can't access any from my home's lan. I need to do a ssh proxy jump to a PC from work to be able to connect for e.g. to my internal nas at home. I checked the routing tables and they seem fine. The tailscale instance running at home is inside a freebsd jail and the one at work runs on a raspbery pi.

    This is the routing table from the tailscala jail at home:

    tailscale:/root@[14:11] # netstat -r
    Routing tables

    Internet:

    Any ideas what might be the problem?
