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).
Hope that helps
Marc
