ISA server 2004 with ipv6 bypass
Bypassing ISA Server 2004 with IPv6
Bypassing ISA Server 2004 with IPv6

When IPv6 is active on an interface of an ISA Server 2004, it seems that IPv6 packets are not filtered and bypass the firewall.

I try to send an ICMP IPv4 packet through the network to ISA Server, this packet was dropped, then i try an ICMP IPv6 packet which successfully works !

The same kind of test was successfull with a TCP connection using IIS 6 and IPv6.
