We have a need to reach a private lab network through our corporate network. No private traffic allowed through the corporate network. Neither the private network allows the corporate traffic.
Currenly we are exploring the possibilities of accessing the private labs located far away.
One of the solutions we are planning is having a private network in our location and establish the tunnels between the two private networks, so that the traffic passes through the tunnels without disrupting the regular corporate traffic. We also can not change the configurations on the corporate routers.
So, we plan to have a router(possibly a Solaris box) in each private network with one interface on the corporate network and establish the tunnel between the two routers.
I need help in how to configure the GRE tunnel between two Solaris boxes or two Windows boxes which will act as routers.
Please help me with detailed configuration.
