+      3. Access the network through a "tuntap" interface.
+         The "ethernet card description" must be set to "tun".
+
+         TUN/TAP provides packet reception and transmission for user
+         space programs.  It can be viewed as a simple Point-to-Point
+         or Ethernet device, which instead of receiving packets from a
+         physical media, receives them from user space program and
+         instead of sending packets via physical media writes them to
+         the user space program.
+
+         Prerequesties:
+         - Make sure the "tun" kernel module is loaded
+           # modprobe tun
+         - Make sure IP Fordwarding is enabled on your system
+           # echo 1 >/proc/sys/net/ipv4/ip_forward
+
+         A virtual network configuration script is required and the
+         default is /usr/local/BasiliskII/tunconfig unless you specify
+         a different file with the "etherconfig" item.
+
+         This script requires you that "sudo" is properly configured
+         so that "/sbin/ifconfig" and "/sbin/iptables" can be executed
+         as root. Otherwise, you can still write a helper script which
+         invokes your favorite program to enhance a user priviledges.
+         e.g. in a KDE environment, kdesu can be used as follows:
+
+           #!/bin/sh
+           exec /usr/bin/kdesu -c /path/to/tunconfig $1 $2
+
+      4. Access the network through the user mode network stack.
+         (the code and this documentation come from QEMU)
+
+         By setting the "ethernet card description" to "slirp",
+         Basilisk II uses a completely user mode network stack (you
+         don't need root priviledges to use the virtual network). The
+         virtual network configuration is the following:
+
+           Basilisk II <------> Firewall/DHCP server <-----> Internet
+           (10.0.2.x)      |         (10.0.2.2)
+                           |
+                           ----> DNS server (10.0.2.3)
+                           |
+                           ----> SMB server (10.0.2.4)
+
+         Basilisk II behaves as if it was behind a firewall which
+         blocks all incoming connections. You can use a DHCP client to
+         automatically configure the network in Basilisk II.
+
+         In order to check that the user mode network is working, you
+         can ping the address 10.0.2.2 and verify that you got an
+         address in the range 10.0.2.x from the Basilisk II virtual
+         DHCP server.
+
+         Note that ping is not supported reliably to the internet as
+         it would require root priviledges. It means you can only ping
+         the local router (10.0.2.2).
+
+         When using the built-in TFTP server, the router is also the
+         TFTP server.
