Hello,
have some doubts here :)
as I get it:
R1-R2 link has 10.1.12.0/24 subnet, 2001:DB8:3002::/64
R2-R4 link has 10.1.4.0/24 subnet
ipv4 src 10.1.4.4 gets translated to 2001:DB8::2
(200:DB8::/96 is ipv6 nat prefix)
now does R1 have 2001:DB8::/96 prefix in its routing table?
and then
2001:DB8:3002::1 is being translated to 10.1.24.2
does R4 have prefix 10.1.24.0/24 in its table?
maybe we should translate 2001:DB8:3002::1 to 10.1.4.1
or something like that?
Please provide your detailed ipv6 NAT config on R2,
(with ipv6 nat prefix, etc..)
TIA
Petr
