Usage: /usr/bin/pesto [OPTION]... PATH

  -A, --add		Add following specifiers to forwards
  -D, --delete		Delete following specifiers instead
  -C, --clear PIF	Clear forwarding table for given PIF
  -t, --tcp-ports SPEC	TCP inbound port forwarding
    can be specified multiple times
    SPEC can be:
      'none': don't forward any ports
      [ADDR[%IFACE]/]PORTS: forward specific ports
        PORTS is either 'all' (forward all unbound, non-ephemeral
        ports), or a comma-separated list of ports, optionally
        ranged with '-' and optional target ports after ':'.
        Ranges can be reduced by excluding ports or ranges
        prefixed by '~'.
        The 'auto' keyword may be given to only forward
        ports which are bound in the target namespace
        Examples:
        -t all         Forward all ports
        -t 127.0.0.1/all Forward all ports from local address
                         127.0.0.1
        -t 22		Forward local port 22 to 22
        -t 22:23	Forward local port 22 to 23
        -t 22,25	Forward ports 22, 25 to ports 22, 25
        -t 22-80  	Forward ports 22 to 80
        -t 22-80:32-90	Forward ports 22 to 80 to
			corresponding port numbers plus 10
        -t 192.0.2.1/5	Bind port 5 of 192.0.2.1
        -t 5-25,~10-20	Forward ports 5 to 9, and 21 to 25
        -t ~25		Forward all ports except for 25
        -t auto	Forward all ports bound in namespace
        -t 192.0.2.2/auto Forward ports from 192.0.2.2 if
                          they are bound in the namespace
        -t 8000-8010,auto Forward ports 8000-8010 if they
                          are bound in the namespace

  -T, --tcp-ns SPEC	TCP port forwarding to init namespace
    SPEC is as described above
  -U, --udp-ns SPEC	UDP port forwarding to init namespace
