[44net] Local Hot-Standby Question

All, I wish to test a remote site from the QTH via Ethernet. The remote location has its own Internet connection I'd also like to utilize. I intend to set it up in the following manner: tunl0 <<>> 44.60.44.128/25 ROUTER-X <<ETHERNET>> ROUTER-Y 44.60.44.1/25 <<>> **AMPR tunl0** - router Y will be connected to router X by [Wireless] Ethernet. I'd like to deliver the RIP 44 announcements to this machine from current router Y, so it may use its own commercial Internet connection (on another carrier) to transmit - through Dynamic DNS, and a local hot-standby script, I intend to have router X to Dynamically possess high availability for my AMPRNet connection - I understand all replies come through my Portal-registered GW until a standby switchover were to take place - I understand the delay may be 5 min - 1 hour * - If I were to do so, would there be any filtering on some of your gateways if the second device transmitted the originating IPENCAP packet for an IP in my registered /24 subnet, instead of my actively registered portal? (If so, what filter are you using? I may be interested in implementing it myself.) * - Would this filter restriction persist if I were to register a subnet to that device? * - Would there be a problem if I possessed 2 GWs in the portal with the same IP, but holding 2 different allocations (in case of fail-over)? Thanks and 73, - Lynwood KB3VWG
