Then it depends on how you want to design the network. You could bridge them together into one LAN and both use the same range of IPs, being careful to avoid collisions (or both use the same DHCP server, which would prevent that). Or you could connect both LANs into a router device and set static routes. Either way, once you have the two segments talking to each other, which DSL is used depends on any policy routing and the default gateway. It isn't going to be as simple as "always use the DSL that is least loaded". Packets coming out of your neighbour's DSL will have a different source IP to packets coming out of yours. There is no way to migrate a TCP conversation from one DSL to the other. You can achieve simple load balancing by deciding which classes of traffic will go which way. For example, an office I know has two DSL connections. It uses one for a VPN to another office, and the other for Internet traffic. To do proper laod balancing you'd have to bond the DSLs - usually only possible when they both are with the same ISP, and would require DSL modems that support that. So that's not likely an option for you here. Cheers, Andy -- http://bitfolk.com/ -- No-nonsense VPS hosting Encrypted mail welcome - keyid 0x604DE5DB
