Ladies and Gentlemen:
I've got an odd problem. Our library needs certain ports open on our
firewall - we're using ISA 2K.
When I create a protocol rule to open those specific ports, it doesn't work.
When I open the firewall completely, it works. When I open all ports except
the ones in question, it works.
The protocol is Z39.50 - apparently it's used quite a bit in library
applications.
I've looked at our protocol rules - everything seems in order. And other
libraries have their firewall configured in this fashion.
Help!
