The simple answer is no: if you want subnet-local broadcast traffic to  
be received, then your DB servers and your clients need to be on the  
same subnet.  Routers are designed and required to not propagate  
broadcast traffic, although you could switch to doing bridging rather  
than routing.  Or, you could set up Sybase's SQL.INI to list all of  
the databases you care about, if I recall correctly...
