This is normally not the case with common +DSL uplinks (they change addresses every day). +To mitigate this problem and get a fixed hostname, there are services called +dynamic DNS or short DDNS. There are lots of [different DDNS services][1], some +are free, some cost money. +Most of those services provide a common API that can be used by freely available +tools to update the address whenever it changes. Mainstream DSL routers have +built-in clients for this API so nothing has to be installed to set up DDNS. + +Besides this unchanging address, a port has to be opened for VpnCloud. This has +to be done in the settings of the DSL router. The default port for VpnCloud +is 3210. This process is different for every router but it usually can be found +under the name of "Port forwarding" or "Exposed ports" (not "exposed host"). + +[1]: http://dnslookup.me/dynamic-dns/ \ No newline at end of file
