Thank you Anssi for your helpful reply. If you do not mind, let's place all the subnet we have on the server into the ACL This will prevent reconfiguration on our side from having an impact on the mirror. Here are the subnets: - 2607:f0d0:1103:120::/64 - 173.193.191.120/30 - 173.193.171.184/29 We will not need to work on the ACL for another five years with this configuration. I am sorry that I did not supply this information initially -- my apologies. I will also use --ipv6 as you suggest. Thank you again Anssi!
