[Samba] WG: Cross subnet browsing + OpenVPN
Hi, Robert Schetterer is right. You will succeed in the end with tap bridging. Bridiging does netbios reach trough. I did this with two XP-Clients 2 Nics build at each a bridge: Both the remote and the local Clients must be in the same subnet.

What about your openvpn config? The tun net must have an entry in your hosts allow. If you work with briding the remote network has to be the same subnet as the local!? Bridging is the best way to have a remote net integrated. I have one logging in form Berlin on my Samba-Domain.

The second machine, REMOTE1, has an internal address of 192.168.1.254 and an external of 192.168.20.4. On openVPN, I have configured client to client and routes and iroutes to allow machines on each network to ping machines at the other end as well as the server IP's. So far so good and I can ping any machine on either subnet from anywhere and get a reply. The servers are configured as Samba servers with the HEADOFFICE machine working as a PDC, DMC and WINS server and the REMOTE1 machine configured as a BDC and WINS proxy. In order to maintain logon facilities in the event of broadband failure, I have replicated the LDAP server from HEADOFFICE to REMOTE1 and updates and password changes propogate successfully from one site to the other. If I try to access HEADOFFICE from REMOTE1 and REMOTE1's subnet it works perfectly but trying to access REMOTE1 from HEADOFFICE and its subnet fails on name resolution while entering \\192.168.1.254\ brings up Windows Explorer and a list of shares. I've included the remote browse entries in smb.conf on the PDC and have WINS Proxying set up on the BDC but I can't get it to push REMOTE1's IP back to the WINS server. Port scanning the internal IP of each machine from the oher end of the tunnel returns a full set of open ports for the services I'm using but no IP. If anyone can spot what I'm doing wrong I'd be grateful.
