Thank good IPV6 is here so we can get rid of this NAT crap, thanks for the video anyway.

[@mehdimj_ir]

I'm using NATv6 for my private network and port forwarding

[@pbrigham]

@@mehdimj_ir ,yes you can, but is adding complexity where is not needed, especially at home, IPV6 can completely substitute IPV4 on a much more efficient and less complex way, and spite we still need gateways to translate IPV4 addresses to IPV6 and vice versa, this is will be temporary until IPV4 is not around anymore. At home you should be using dual stack and use only IPV4 as a backup or for the services out there that strictly require IPV4 connection, that is less and less, more 2 years and 90% of traffic will be IPV6, is already at 50% now.

A network-network translation in IPv6 seems more useful to me, replacing an internally used prefix with one provided by the ISP. I have tried using netmap, but it requires that the NATed IPs be created on the router

Druv Druv. I always like his presentation. Can u maybe sometime give a hint on netmap.

[@Problembaer4]

netmap is over a decade still a mystery to me... good point!

[@mikrotik]

We will see what we can do.

[@SJGsysadmin]

Could this be used as a CGNAT?

[@mikrotik]

We will cover CGNAT in another video, it also makes use of Source NAT.

[@MathiasWesterlund]

​@@mikrotikYES PLEASE a lot of us smaller ISPs are having trouble with figuring out the "Right way" for CGNAT on mikrotik.

[@user-wy2ys7eo8j]

If there are multiple ADSL lines, does it make sense?

[@kareemtharwat]

Need to use ipcloud in Microtik behind isp cgnat

[@nikolashuminosky6987]

what input does in NAT?

[@nick9323]

term color theme is too dark for light bg gns3

[@mikrotik]

Perhaps you are right, thanks.

[@martinsilcher9008]

This is great that MikroTik can do this and everything, but this just sounds like someone was bored one day and said what can MikroTik do? There's no real practical purpose for this.
