[SLE] Hard Drive thrashing?

Hello Linux folks. On my Linux server I set up masquerading and firewall for our internal network. When my wife or myself browsing Internet from any other PC behing the firewall the Linux server's hard drive is thrashing all the time. Does somebody know if it's normal? Does it have something to do with receiving and transmitting datagrams for our internal network?
