+#* reason -- why this script was called, one of: pre-init connect disconnect
+#* VPNGATEWAY -- vpn gateway address (always present)
+#* TUNDEV -- tunnel device (always present)
+#* INTERNAL_IP4_ADDRESS -- address (always present)
+#* INTERNAL_IP4_NETMASK -- netmask (often unset)
+#* INTERNAL_IP4_NETMASKLEN -- netmask length (often unset)
+#* INTERNAL_IP4_NETADDR -- address of network (only present if netmask is set)
+#* INTERNAL_IP4_DNS -- list of dns serverss
+#* INTERNAL_IP4_NBNS -- list of wins servers
+#* CISCO_DEF_DOMAIN -- default domain name
+#* CISCO_BANNER -- banner from server
+#* CISCO_SPLIT_INC -- number of networks in split-network-list
+#* CISCO_SPLIT_INC_%d_ADDR -- network address
+#* CISCO_SPLIT_INC_%d_MASK -- subnet mask (for example: 255.255.255.0)
+#* CISCO_SPLIT_INC_%d_MASKLEN -- subnet masklen (for example: 24)
+#* CISCO_SPLIT_INC_%d_PROTOCOL -- protocol (often just 0)
+#* CISCO_SPLIT_INC_%d_SPORT -- source port (often just 0)
+#* CISCO_SPLIT_INC_%d_DPORT -- destination port (often just 0)
+
+# 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
