CIFS Connection timed out

Hello,

I have problem with mount CIFS.
mount: mounting \\remoteaddress\media on /mnt/test failed: Connection timed out

In syslog is: Sep 16 11:47:49 kernel: CIFS VFS: Error connecting to IPv4 socket. Aborting operation

Strange is that on other device it works fine, so problem will be in AC66U FW (378.55)

Any idea?

Thank you.
Gabriel
