Does the DNS-Changer Bug Affect the FatPipe Device?

No, the DNS Changer Bug is not a FatPipe related issue.

It is a virus that exists on the LAN - the outside world would see the IP address of the WAN interface the packet exits and flag that IP - but it is not a FatPipe related issue - the device on the LAN that is causing the issue/bug would need to be found and quarantined.
