VPN issues through Linksys RVS4000 - can't ping past the router on either side

We have two static ip's with the same ISP approximately 5 miles from each location.  We are using two Linksys RVS 4000 Gigabit Ehternet Security VPN Routers.  Both locations have real-world static ip's from the isp.  One router's LAN interface is set to 10.10.10.x while the other is 10.10.11.x, the tunnel is set to and respectively and is connected with no issues.  We can ping from router to router and I can even open and make changes to either router from one location using the LAN ip address.  We have upgraded the firmware to 1.2.11 which i believe was the latest firmware.  We have turned off all firewall settings on the router, all filters, etc. with no results.  We have used the same config at other locations without these issues.  It is as if something in the RVS 4000's are causing the block.  We have of course spent days on the phone with Linksys / Cisco who have dropped the ball and we were supposed to get to replacements out overnight (Monday) for the two RVS 4000's which did not show.  Called again yesterday to inquire and today we got one of the two.  Have others had this with the newer Linksys products or are there any other ideas?  We have allowed to RVS 4000's to do DHCP and have also tried assigning our laptops with static ips and turning off DHCP with the same results.  We can ping to the LAN of the opposite router but nothing behind it.  To be more specific laptop A can get to the router of location B via the LAN interface, but not to the laptop just behind that router.  Same result both ways.  All systems behind both routers have excellent internet and speeds.

    Did you try to capture related traffic on the remote LAN, e.g. with WireShark?
