+
+# FIXMEs:
+
+# Section A: route handling
+
+# 1) The 3 values CISCO_SPLIT_INC_%d_PROTOCOL/SPORT/DPORT are currently being ignored
+#   In order to use them, we'll probably need os specific solutions
+#   * Linux: iptables -t mangle -I PREROUTING <conditions> -j ROUTE --oif $TUNDEV
+#       This would be an *alternative* to changing the routes (and thus 2) and 3)
+#       shouldn't be relevant at all)
+# 2) There are two different functions to set routes: generic routes and the
+#   default route. Why isn't the defaultroute handled via the generic route case?
+# 3) In the split tunnel case, all routes but the default route might get replaced
+#   without getting restored later. We should explicitely check and save them just
+#   like the defaultroute
+# 4) Replies to a dhcp-server should never be sent into the tunnel
+
+# Section B: Split DNS handling
+
+# 1) Maybe dnsmasq can do something like that
+# 2) Parse dns packets going out via tunnel and redirect them to original dns-server
