NAT on IPv6?

Question asked by Hugo van der Kooij on Mar 12, 2018

I am just building a new LAB. In it I have 2 options to provide all systems with IPv6 connectivity.

  1. Use the Single /64 subnet on the outside and use 2001:db8:: subnets on the inside with NAT enabled.
  2. Setup a link with TunnelBroker.net and get my own /48 subnet and use public IP addresses all the way.

 

I have to use NAT on IPv4 traffic anyway. But if I go for option 1 I still have to fill in the IPv6 address for NAT.

But the first option is the one I have been using for a while now. I am not sure how well NAT work on IPv6 traffic in R80.10 so I am a bit sceptical yet on trying option 2.

 

Anyone willing to share their experiences?
