Pieces:  Cisco 3845 router, connected to the Edge router at the Core.  Customer has /30 WAN and /27 LAN.  
x.x.x.1 is used on the Cisco, connected to x.x.x.2, customer firewall.   When we go out to check, the customer cannot surf to a SPECIFIC domain, a .net, but can surf to every other domain on the planet, including the .com side of his domain.  All other customers can surf to this .net address.  The tricky thing is that if we connect directly to the router on gig 0/1, the LAN side, taking the firewall and LAN out of the picture with a ordinary laptop, assign the .2 address to that laptop, we still cannot reach the domain in question.   However, and this is the weird part, if we assign our laptop ANY other IP in the LAN subnet, surfing is working just fine.  Its JUST the .2 address...We are baffled...any help would be appreciated.
