Two options implement your own replication model using triggers or opt
for IBReplicator
This is a commercial replication tool designed to handle N-way replication.
The tool is maintained by IBPhoenix
http://www.ibphoenix.com/main.nfs?a=ibphoenix&s=1086124693:485378&page=ibp_replicator

There are some good papers that discus replication in general and more
specifically Interbase / Firebird
on this site as well.
If you are after a shareware replication tool :
