Put the dsl modem into bridge mode and let the PIX get the public IP address.<br />
Or setup a script on a pc to ping something across the vpn tunnel every once in a while to keep the tunnel up.

The isp will not allow me to set the modem to bridge mode. &nbsp;I don't have any pc's at the remote. &nbsp;Only priners and thin clients. &nbsp;Is there a way to have the pix run the ping?

I have created a Site to Site tunnel. &nbsp;On one end, the ISP will only give a static IP by &quot;pushing it down&quot; to their DSL modem. &nbsp;I have the Pix behind the ISP modem/router. &nbsp;The ISP Router issues a private DHCP address 192.168.5.x to the Pix outside interface. &nbsp;The tunnel comes up fine initially but after an inactivity timeout the tunnel will not rebuild until the equipment &nbsp;(ISP router and Pix)is reset. &nbsp;

I have created a Site to Site tunnel.  On one end, the ISP will only give a static IP by "pushing it down" to their DSL modem.  I have the Pix behind the ISP modem/router.  The ISP Router issues a private DHCP address 192.168.5.x to the Pix outside interface.  The tunnel comes up fine initially but after an inactivity timeout the tunnel will not rebuild until the equipment  (ISP router and Pix)is reset.  

site to site tunnel b/n 2 cisco pix 501 requires reset to re-establish tunnel after idle timeout
