Private interfaces and exceptions

Novell Cool Solutions: Question & Answer

Posted: 30 Jun 2005

Q:
In FILTCFG is it possible to mark an interface as private or public? We have a server with a lot of NICs, private and public, but all are set to private and I've never had any problem with it. Does this have an effect on filtering exceptions?

A:
Yes, it does affect your exceptions. For example, if NDS problems prevent filtsrv from reading filters out of NDS, all traffic to and from an interface designated as public will be blocked. Traffic to private interfaces will be allowed. Consequently, if both are marked as private, and you have some NDS issue, you could have a situation where you have no filtering.
