Description
"vboxmanage natnetwork" list displays wrong IPv6 prefixes
How to reproduce:
vboxmanage natnetwork add --netname ISP-Alpha \
--network 172.31.255.0/24 \ --enable \ --dhcp no \ --ipv6 yes
vboxmanage natnetwork add --netname ISP-Beta \
--network 10.222.222.0/24 \ --enable \ --dhcp no \ --ipv6 yes
vboxmanage natnetwork list
Output: Name: ISP-Alpha Network: 172.31.255.0/24 Gateway: 172.31.255.1 IPv6: Yes IPv6 Prefix: fd17:625c:f037:2::/64 Enabled: Yes
Name: ISP-Beta Network: 10.222.222.0/24 Gateway: 10.222.222.1 IPv6: Yes IPv6 Prefix: fd17:625c:f037:2::/64 Enabled: Yes
The printed IPv6 prefix is the same(!), and wrong(!), for both configured networks. When turning on sending router advertisements (in the GUI, the corresponding parameter for vboxmanage seems to not exist), both networks use different prefixes (as expected), none of them is fd17:625c:f037::/64 (i.e. the output above is wrong in both cases).
The issue should be fixed in VirtualBox 6.1.34. Closing.
