An example operation may include one or more of storing a first IPv6 address of a router assigned by a first carrier and a second IPv6 address of the router assigned by a second carrier, assigning a plurality of IPv6 addresses of the first carrier to a plurality of devices on a local area network (LAN) served by the router, receiving a packet from a device included on the LAN, where the packet comprises an IPv6 address of the first carrier assigned to the device, replacing the IPv6 address of the first carrier within the packet to the second IPv6 address of the router assigned by the second carrier, and transmitting the packet to the Internet via an IPv6 connection of the second carrier.

IPV6 address translation for compatibility with multiple carriers

A communication system includes a data network that is coupled to various nodes, including routers. In one example arrangement, a first router is part of a first local network and a second router is part of a second local network. Each router includes a security gateway module and a keep-alive module. The security gateway module is capable of establishing a secure link, such as one according to an Internet Protocol Security (IPsec) protocol, over the data network. The keep-alive module sends one or more ping messages over the secure link to the remote router (or a node coupled to the router), which responds with appropriate ping replies to indicate that a link is alive.
