Does anybody know how to do this? Furthermo= Your setup is reasonable. You don't even need to dual boot the client behind the firewall, let it run dual/stack too. However, your setup will work the best if both the firewall and the client have publicly routeable ipv4 addresses. In other words NATing ipv4 via your firewall will probably break things. Ipv6 traffic from your client to your freenet6 enabled ipv6 router should work just fine. > re, > how can an application detect system's configuration (IPv4/IPv6, IPv4-only, > IPv6-only)? By looking at the configured address. Most applications that are enabled for ipv6 are capable of running both ipv4 or ipv6 by abstracting the ipaddress type and changing to use a few different function calls (inet_ntop and inet_pton mainly). --- Mark atkin901 at NOSPAM yahoo dot com (!wired)?(coffee++):(wired);
