Packet Filters May Not Apply in ISA Server (300199)


The information in this article applies to:

  • Microsoft Internet Security and Acceleration Server 2000
This article was previously published under Q300199

SYMPTOMS

If you create an IP packet filter to deny all traffic in ISA Server, traffic may still flow through.

CAUSE

This issue can occur if you create a "deny all" packet filter and you have multiple IP addresses that are bound to the external network adapter.

RESOLUTION

When you create IP packet filters, create a packet filter for each IP address that is bound to the external network adapter. By default, the packet filter only applies to the first bound IP address on the external network adapter (the default IP address for each external network adapter on the ISA Server computer).
