NFS/Share from Intercon and Wollongong's NFS Client do not work across
ComTalk gateways because of lack of support for splitting up and
encapsulating larger UDP-type packets over AppleTalk/LocalTalk. These
vendors are aware of this problem and are working on a fix. There are no
problems supporting TCP-based services, such as Telnet, SMTP, FTP.
Other than this compatibility issue, these products are very fast, and
have a comprehensive set of security options.
