I need to access my linux server which is behind a router by the same name or IP, both inside and outside my network.

1. (Clients are mac/linux/win).
2. I've tried the router/dyndns solution… but if I ping the dyndns IP (my router's ip) from *within* my network, it doesn't forward; it stops at my router.
3. Is VPN the only solution for this?
4. Two steps: 1.) configure your router to allow access to the server by whichever service you need, e.g., http, ftp, smb, etc. 2.) Look into dyndns.org. It allows you to give a name to a non-static IP so you can access it from outside the router. There is also software available to automagically update the dyndns.org DNS servers if your home IP changes.
