Tunneler instead of Router on Remote side

Hey guys,

can i reach Non-Ziti Clients on a Remote Network just with a Tunneler on Remote side?

I'm asking because i see this picture in the documentation:

Maybe i can create routes to the used 100.xx network on all target devices.

You need any tunneler software in order to accomplish this. Routers can be configured as tunnelers along with the regular desktop-style tunnelers can all be used to "host" services. So sure, you can do this. As long as the tunneler can access the destination underlay service, you can use any tunneling software to do this (router, desktop edge or even mobile edge).
