Hi Ernie, are the FreeBSD boxes in the two locations connected like this? --- router a/1 -> ADSL / beastie1 \ --- router b/1 -> Frame Relay And in the other location vice versa? Then you should install gated (or similar) and enable OSPF on the FreeBSD machines over the two links. Dynamic routing is the only thing which can help you. Perhaps you would like to install a second FreeBSD box in each location and connect the second box with _both_ routers. Because if a single box fail the other could take over (if the rest of the network is designed for that).
