IPv4 and IPv6 don't interoperate, and while there are mediocre technologies for getting from IPv6-only clients to legacy IPv4-only servers such as NAT64+DNS64, the IETF gave up on trying to get from legacy IPv4-only clients to bleeding edge IPv6-only...

For routing purposes, prefixes vary from /9 to /127; routing a /56 is fine.  However, there is a very strong bias toward in 64 bit:64 bit split in subnet and host parts of addresses, and it's best practice to make all regular vlans be /64 except for ...

a) While I believe you can configure the IPS side using ASDM, you will get better results using something like IME or CSM.b) No, you will need separate IP address for the ASA and the IPS.  Furthermore, the IPS will have to use the management interfac...

I'm confused about use of management interfaces on an ASA 5525-X we're about to power up, eventually replacing an ASA 5520.  On the 5525-X, the management interface is   (1) management-only   (2) overloaded for use by the ASA and the IPS module, usin...

Almost enough information.  It would help to know how many IPv4 addresses you have on the outside of the firewall, and how you plan to use them.  For a scenario with:* ASA software 9.1(1)* 1 IPv4 address on the outside interface of the firewall, say ...
