Ipv6 nat-pt

abhustler

Im running into a brick wall trying to configure NAT-PT. I currently have a lab with six routers all running IPV6 and IPV4. Off of one of my routers I have a server with an IPV6 address of 2222:7e00:11:11:11::3. This can communicate fine with any other IPV6 address on my lab. What I want to have happen is allow the IPV6 only server (and many others devices later) communicate with IPv4 addresses on my network and eventually ipv4 websites. I've configured what I thought would accomplish this but keep getting errors in the debugs

*IPv6 nat is configured on both interfaces

ipv6 nat v6v4 source list Source_Nat interface FastEthernet0/0 overload
ipv6 nat prefix 2064:7E00::/96 v4-mapped Source_Nat
!
!
!
ipv6 access-list Source_Nat
permit ipv6 2222:7E00::/96 any

When ever I try pinging 2064:7e00::6400:1 (last 32 bits equivelent of 100.0.0.1 which is a pingable ipv4 address on one of my routers) from the server the routers displays this message - Mar 2 15:25:32.397: IPv6 NAT: Dropping v6tov4 packet

Is there something I'm missing?

have you added ipv6 nat to all the interfaces you want to participate in NAT-PT?

Might want to post a picture of your topology with IPs...it would be easier to see where you are wanting your v4 and v6 traffic to go.

Everything is working fine now. When in doubt check the small stuff. Just had a typo in the ipv6 nat prefix.
