The listener listens for new connections on port 1525. Incoming connection requests
are then mapped to an arbitrary other port; could it be this is what happens? Consequently, the router can block this connection. There is an option (which I can't recall right now - sorry) to force sql*net to use one and only one port, you'll need to check the doc.

BTW the "standard" port for oracle is 1521, the 1521/1525 combination is from the times net V1 and V2 were used concurrently - V1 listening on 1521, V2 on 1525.
