     - We could establish a tunnel between our sites which could make it possible to access our own servers by connecting to the other's LAN using special addresses. The 'other' LAN could then route the connection back through the tunnel to the desired destination. Of course this scheme would break down if both sites lost their fiber connection simultaneously.     - We could establish a tunnel between our sites which could make it possible to access our own servers by connecting to the other's LAN using special addresses.

     -   We could have a publicly accessible server somewhere in the Internet which each of us could make tunnels to and hence obtain the same advantages as above plus the possibility to still have access if e.g. my fiber went down **and** Steve was offline for whatever reason     -   We could have a publicly accessible server somewhere in the Internet which each of us could make tunnels to and hence obtain the same advantages as above plus the possibility to still have access if e.g. my fiber went down **and** Steve was offline for whatever reason

-Connecting back to our servers through the tunnel does not require actions beyond what is described above. If, however, it should be necessary to use the sub-delegated addresses as source address for sending mail, further action is required.+Connecting to our servers through the tunnels does not require actions beyond what is described above.

 In order to have our sent email properly accepted by foreign mail server it is necessary to provide reverse name lookup for the mail servers. For practical reasons we decided to delegate the administration of the delegated sub-domain to the one that uses it. Details of the name space delegation is described in [[cross-allocation|IPv6 Cross allocation]] In order to have our sent email properly accepted by foreign mail server it is necessary to provide reverse name lookup for the mail servers.
