I have a Linksys BEFW11S4 and previously I had a BEFSR41. Both boxes
came up and worked with absolutely no problem. Several of the people I
worked with at HP had the same boxes. JABR also has the BEFW11S4. 

The Linksys BEFSX41 box also serves as a VPN endpoint. The D-LINK box
you have appears to be the equivalent to the BEFSR41. In any case, I
found that the Linksys boxes were significantly cheaper by mail order. 
The BEFSR41 should be available for under $50.
