Anyone seen these routers leak LAN to WAN? We hooked up a new customer who has one of these and while it is establishing a PPPoE session on the WAN side, we are also seeing his LAN side MAC address, we are seeing a rogue DHCP server from him, and can even log into his router at 192.168.2.1 with no password and screw around with stuff. We can't log in via his WAN address though, as expected. The performance to his LAN address via the WAN seems sluggish, as if the sneak path isn't full bandwidth. I guess he could have connected a cable from the Internet port to a LAN port and then another LAN port to our POE, but I'm pretty sure no. I was blaming this on the Mercury WiMAX CPE we used for the first time on this install instead of Greenpacket, since its default IP address is 192.168.2.1. I even opened a ticket with Mercury claiming they had a problem with their bridged mode. But now I realize it is the Belkin router. Oh, and the Mercury CPE is pretty nice, except I miss the diecast articulating mount. It appears to be made by KZ Broadband Technologies.
