Please help! Cablenut settings for my connection. Thanks

Could someone please help me on setting up Cablenut and other tweaks for my connection.

1. DSL - PPPoE

2. TPG Australia, 256 Kbps Download / 64 Kbps Upload

3. TCP/IP Analyzer results:

TCP options string = 0204055001010402
MTU = 1400
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1360
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 63888
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 63888

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
522240 (MSS x 48 * scale factor of 8)
261120 (MSS x 48 * scale factor of 4)
130560 (MSS x 48 * scale factor of 2)
65280 (MSS x 48)
bandwidth * delay product:

Your RcvWindow limits you to: 2555.52 kbps (319.44 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1022.208 kbps (127.776 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 39 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

4. OS: Windows XP

Thanks.

I also ran a speed test at the following site:

My result: 212.3 Kbps
