PIX and IPv6 help needed

Hi,

I am trying to enable my PIX for IPv6, so that I can connect from my internal LAN into my DMZ. But I run into some problems and I am not sure if I understand the IPv6 inplementation on the PIX correctly.

In IPv4 I can create a connection from host A on an interface with a higher security level to host B on an interface with a lower security level, right? I do not need to configure any access lists to do that, the PIX automatically takes care that traffic that belongs to that connection can pass from A to B and from B to A, right ? I tried the same thing for IPv6, and I could send traffic from A to B, but the traffic back from B to A was blocked ( icmpv6 this example, but also tcp connections didn't work ).

So I would like to know if the PIX is allready able to do for IPv6 traffic. Can it only do static access-lists for IPv6 ??? Or should it be able to the same things for IPv6 as for IPv4 ( especially the statefull inspection and lets call it "dynamic access list" features ) ?????

Thanks, Ruediger

Re: PIX and IPv6 help needed

When entering IPv6 addresses in commands that support them, simply enter the IPv6 address using standard IPv6 notation, for example ping fe80::2e0:b6ff:fe01:3b7a. The security appliance correctly recognizes and processes the IPv6 address. However, you must enclose the IPv6 address in square brackets ([ ]) in the following situations:

You need to specify a port number with the address, for example [fe80::2e0:b6ff:fe01:3b7a]:8080.

The command uses a colon as a separator, such as the write net and config net commands. For example, configure net [fe80::2e0:b6ff:fe01:3b7a]:/tftp/config/pixconfig.
