|---|
| 85 | |
|---|
| 86 | B<prep_gateway.pl> laods the necessary kernel modules for low-level bridging |
|---|
| 87 | configures the local sshd to allow it, restarts that sshd, and installs the |
|---|
| 88 | given key in root's authorized keys. |
|---|
| 89 | |
|---|
| 90 | If the gateway supports DETER gateway, it setablishes outside connectivity and |
|---|
| 91 | adds a host rout to the given peer. |
