    FYI, the comcast/smc box uses unnumbered bridging between comcast and the customer site.
    Hence when logged into the smc box, there is a WAN IP, but no default gateway for the smc box.
    When another router is connected (especially to provide VPN services), the other router needs to be configured in a 255.255.255.252 (30bit) subnet, with the default gateway being the WAN IP of the smc box, and the WAN IP of the router being one less (so 174 is the GW, and the WANIP is 173).

    FYI: I did use/copy a lot of info from many other posts.
    Problem is the auto-reconnect feature does NOT always work. So far it has worked for a total of 3 weeks, and NOT worked for a total of 3 weeks. History is 2 weeks good, 2 weeks broken, 1 week good, 1 week broken. We have to manual connect (click connect button on the VPN web page for the linksys BEFVP41. We have reset both routers to factory, reflashed, reset to factory again, and resetup everthing in routers - did not help. We contacted comcast and had them test the cabling - did not help. Choices are to use different brand VPN routers or created an automated script to click on that connect button. Anyhelp would be appreciated.
