Hi everybody, apart from the clients in our Samba [1] server's subnet, we would like to allow access from some selected outside machines as well. Those people enter our network via VPN and are associated IPs that look like the ones below: vpn-82-51.test.de --> 173.237.82.51 vpn-84-13.test.de --> 173.237.84.13 Those users receive a new IP address every time they make a new VPN connection; so the addresses are dynamic. As not each and every of our VPN users is to be allowed onto our server, I thought about setting up some kind of dyndns client on the outside machines that associates the dynamic VPN IP address with a dyndns hostname, like that: vpn-82-51.test.de --> 173.237.82.51 someaccount.dyndns.org --> 173.237.82.51 I then modified smb.conf (173.237.79. is our subnet): hosts allow = 173.237.79. someaccount.dyndns.org But alas, it does not work: I receive "connection denied" when I try to connect to the server from the outside client machine. However, if I modify the line above for testing purposes, like hosts allow = 173.237.79. vpn-82-51.test.de hosts allow = 173.237.79. 173.237.82.51 it works as expected and I am allowed to access the shares. Why does the dyndns adress not work whilst the vpn-82-51.test.de address does, when both resolve to the same numerical IP address? Any other ideas how to solve the task?
