TomatoUSB

I'm running Tomato Firmware v1.28.8754 ND USB vpn3.6 on ASUS WL520GU, historically with Windows machines. I also mount USB sticks or (NTFS-formatted) hard drives as network shares as needed. Windows machines see those shares just fine.

Recently I added a macbook pro (running OSX 10.8 Mountain Lion) to my network. I am experiencing two issues:

1. Typically, the Mac shows all available shares (i.e. the machinename) in the Finder. This isn't always the case - sometimes I see it, sometimes not. At the same time, Windows machine reads the share just fine.

2. Even when the Mac sees the router in the Finder, it cannot read it, and it doesn't give any additional details as to why (just "Connection Failed")

My settings for USB and NAS are: (just the checked items)
core USB support
USB 2.0 support
USB Printer support
bidirectional copying
USB Storage support
file systems support Ext2/ext3, NTFS, FAT
automount

File sharing:
Enable file sharing: Yes, no authentication (also tried with authentication, no difference in outcome)
Auto-share all USB partitions (read/write)
options: Master browser, WINS server

Any help will be appreciated. Thanks!

Additional information:

when attempting to connect to the router share by browsing into the router on the network, Mac displays a dialog "There was a problem connecting to the server "xxxxx" "The version of the server you are trying to connect to is not supported. Please contact your system administrator to resolve the problem."

Macs do not natively support NTFS. Google OS X NTFS to find solutions.

What if the USB drive is actually FAT32 formatted and not NTFS? I also tried unchecking NTFS from the file systems support to see if it would make a difference, but it did not.

Posting for reference in case others run into this issue. It has to do with the version of the smb protocol Apple supports. A workaround exists for OSX Lion, but not for Mountain Lion.
