List transactions *relayed* by my full node?
Blockchain.info lists the first IP address it sees a new transaction from.

If you aren't the one creating the transaction, and aren't accidentally the node right in between the node that does and blockchain.info, it's unlikely that you're the first to do so. Furthermore, they may not even be connected to you the whole time.

To see what transactions are being relayed, start bitcoind with -debug=net, and look for 'inv' messages in the debug.log file.
