The activity light flashing is a normal occurrence on the router. You want
to know if packets are leaving a machine, then use Ethereal (free use
Google) will tell you.

You want to see what connections are being made on the machine; you can use
Active Ports (free). I like to put an Active Ports short-cut in the Startup
folder to see what's happening at the boot with a clear picture of events.

You want to see what's using SVChost.exe because Spyware or a Trojan can
use SVChost.exe on their behalf; you use Process Explorer (free) to look at
the processes that are using SVChost.exe.

You want to better protect the LAN, then use IPsec that's on the NT base
O/S to supplement the router and any host base FW on the machine.

The AnalogX zip file has a SecPol file that can be applied to the machine
to protect the ports.

You can use the Host to help protect on outbound connections by spyware.

BTW, if svchost.exe is not running out of the system32 directory, it's a
Trojan.
