+         (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.
