| 79 | =head1 SYNOPSIS |
|---|
| 80 | |
|---|
| 81 | B<setup_bridge.pl> Connects the established ssh tunnel (a tap interface) to |
|---|
| 82 | a local interface through a bridge interface. Traffic on the local interface |
|---|
| 83 | will cross the network over the ssh tunnel and be released onto the net via a |
|---|
| 84 | symmetrical setup on the peer. |
|---|
| 85 | |
|---|
| 86 | The interface to attach can be given either by its interface or an address/DNS |
|---|
| 87 | name to reach. In either case, all IP addresses are removed from the |
|---|
| 88 | bound interface. |
