[Samba] Samba over bridged ethernet VPN

[Daniel Bye]

Hi all,

I have Samba 3.0.32 on FreeBSD-7-RELEASE, set up to act as a very simple
workgroup file server (i.e., no domain or anything fancy like that). It
is the latest version of Samba available in ports.

I am seeing timeouts and connection reset errors in my per-client logs such
as the following. For clients on the local LAN, the errors don't cause any 
real problems. However, for remote clients connected over OpenVPN in bridged 
Ethernet mode over cheap domestic ADSL lines, they result in the clients 
being unable to open or otherwise manipulate files on the server.

...and so on.

This client machine is running WinXP Pro, but we are seeing the same for
WinXP Home, Vista HP, FreeBSD and Linux-based clients. I have found several
references to the same problem in numerous mailing list archives and bug
reports around the web, but none of them seems to have a definite fix.
Anyone know of anything I can try here?

Thanks for any help or insights you can offer...

Dan
