As a side question, I was wondering why the system command ifconfig(in

GW is Linux-side, Host is lwIP-side, it's that simple :)

Am I correct to remember some changes in this area? Plus he says he's using 1.4.x...?

(I can't help on the Multicast/IGMP part).

Unfortunately, I can't really help here, too (and Frédéric who wrote that part doesn't seem to be too active here, any more). Anyway, as I think you're speaking of registering lwIP as multicast consumer *inside* your linux, is this supported by tapif at all? Normally, switches implement this via IGMP snooping and I'm not sure linux does this internally...
