@item guestfwd=[tcp]:@var{server}:@var{port}-@var{cmd:command}

to the character device @var{dev} or to a program executed by @var{cmd:command}

which gets spawned for each connection. This option can be given multiple times.

You can either use a chardev directly and have that one used throughout Qemu's

lifetime, like in the following example:

@example

# open 10.10.1.1:4321 on bootup, connect 10.0.2.100:1234 to it whenever

# the guest accesses it

qemu -net user,guestfwd=tcp:10.0.2.100:1234-tcp:10.10.1.1:4321 [...]

@end example

Or you can execute a command on every TCP connection established by the guest,

so that Qemu behaves similar to an inetd process for that virtual server:

@example

# call "netcat 10.10.1.1 4321" on every TCP connection to 10.0.2.100:1234

# and connect the TCP stream to its stdin/stdout

qemu -net 'user,guestfwd=tcp:10.0.2.100:1234-cmd:netcat 10.10.1.1 4321'

@end example
