10000 a day? That's nothing.
Our companies web presence is behind a PIII 800, with 376MB RAM, and it NATs 
in excess of 10000 individual web requests a minute, just to one of the 
webservers!
Add the mail server, the support system, the bug trackers, etc, etc.
Currently handling nearly 40000 connections, with peaks of over 60000.
Pushing upwards of 40Mbps at normal peak.
And all the while being the end point for several IPSEC VPNs.
It can quite happily max out the 100Mbps connection, as it is now (hasn't done 
that before!) with a cpu usage of ~40%.
