[c-nsp] Device for mapping IPv6 to IPv4-addresses

[Lars Lystrup Christensen]

Hi Andreas

I would suggest an ugly a NAT-PT device, capable of doing both v4 and v6. However, there is no guaranties of the serverpart working correctly, as you might have the same issues as with IPv4 NAT.

You should be able to do the NAT on any Cisco router capable of doing IPv6 and NAT. Don't use L3 switches, as they might not support this to satisfactory.

Take a further look at http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-nat_trnsln_ps6350_TSD_Products_Configuration_Guide_Chapter.html

	Hello,

I need to realize an IPv6-island inside an IPv4 network. To connect my 
IPv6-island to the IPv4-world I need a network-device with the following 
features:
- the IPv6-addresses need to be mapped (dynamically) to IPv4-addresses 
for internet-connectivity.
- the IPv6-Island will contain about a hundred computers.
- some servers in the IPv6-island have to be reached from the 
outside-world by a static-IPv4-address.
- the network is based on gigabit ethernet.

what possibilities do I have to realize this scenario ?

thanks for help && happy weekend,

Andreas Mueller
