OS X: Samba shares not connecting when connected via vpn

Question

VPN

I connect from home to the office network via VPN. I'm trying to mount the balls on the office NAS - they seem to be mounted, but at the same time the window with "connecting to smb:// .." does not disappear and the finder hangs for a while. All this is accompanied by the following:

05/11/11 23:10:37 kernel smb_iod_reconnect: Reconnected share… with server 192.168.0…

After the last message, the finder hangs, but the connection to the NAS also disappears. Interestingly, at the same time, the bootcamp Windows launched in parallel mount everything with a whistle, i.e. the problem is precisely at the OS X level.
I googled diligently, but I did not find anything on this issue. Where to dig at least?
