+%package client
+Summary:        Client component of phantun
+Requires: (%{name}-selinux if selinux-policy-%{selinuxtype})
+
+%description client
+Phantun Client is like a machine with private IP address
+(192.168.200.2/fcc8::2) behind a router. In order for it to reach
+the Internet, you will need to SNAT the private IP address
+before it's traffic leaves the NIC.
+
+%package server
+Summary:        Server component of phantun
+Requires: (%{name}-selinux if selinux-policy-%{selinuxtype})
+
+%description server
+Phantun Server is like a server with private IP address
+(192.168.201.2/fcc9::2) behind a router. In order to access it from
+the Internet, you need to DNAT it's listening port on the router
+and change the destination IP address to where the server
+is listening for incoming connections.
