Netmask will be 255.255.255.0, broadcast will be 192.168.1.255, GATEWAY 
will be the router's LAN-side IP (probably 192.168.1.1) and the DNS 
Server returned by "host zahav.net.il" is 192.117.172.16

If you have problems, be sure that your choice of static IP is not 
somehow interfereing with the router's DHCP pool.  (Linksys has rules 
that I've never really understood. YMMV)

Also, I strongly suspect that you would have been happily surfing 
several hours ago, had you given all the information above in your 
original post.

Good luck!
