I am attempting to utilize BackupPC on a Fedora server to backup a remote client (Win7).
As I understand it, BackupPC's primary mechanism for finding clients is performing an
nmblookup <clientname>
This works fine for computers connected to the local network.
My issue is extending (?Samba's?) search to encompass our other network - the point-to-point VPNs
Using OpenVPN, we have a number of road warriors who connect their VPN to gain access to the samba server and it's shares.
Each has a unique static IP address in the 10.30.251 range and when connected, I can find them but not samba
i.e.
#> ping john_laptop
--- john.inspirah.com ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2001ms
rtt min/avg/max/mdev = 9.900/14.764/24.388/6.805 ms
#> nmblookup john_laptop
querying john_laptop on 127.255.255.255
querying john_laptop on 10.30.7.255
name_query failed to find name john_laptop
How to I configure Samba or whatever Linux service is necessary to query the 10.30.251.255 network as well

I've attached a copy of our smb.conf - with comments filtered out
