I very much doubt this is going to work correctly! If the VF router is likely to still attempt to log into the VF "Challenge Handshake Authentication Protocol" (CHAP) servers, and when it fails, it'll most likely just go into a loop.
Be aware that Vodafone's equipment is VERY locked down, such that if you need to perform certain tasks you have to call customer services to attempt the settings for you - obviously that will be a problem too!
One telling observation is the lack of third-party, independent reviews gushing about the hardware - there aren't any!!! Oh, and the router you are looking at was almost certainly the property of Vodafone and not the person who VF had loaned it to!
