[Samba] Samba Share : Connection refused

[Sascha Wiechmann]

Hi everyone,

I have a small issue on our main samba server. We added a hardware 
firewall with different zones and now I want to get access from new 
development LAN (192.168.4.) to samba (192.168.0.) but I get information 
about access denied on windows 7 (net use Error 5).
Firewall is open to all internal LANs. I checked the smb.conf and, for 
me, it seems to be fine. I added hosts allow before holiday and it 
worked, but after my holiday access is denied. Maybe I am blind and you 
may give me a hint, please...

Log :

[2018/07/09 09:37:06.872551,  0] ../source3/lib/access.c:338(allow_access)

Thanks for your efforts !
