Yeah, I realize that I need NAT (or PAT in Cisco terms), but I thought (I 
admit I didn't check) that the AP might do the NAT.

Thing is, I was wondering why I need a router. I don't need it to do any 
routing decisions (unless I want to share files between connected PCs, 
which I don't). I do need NAT, but I kind of thought an AP would do that.

Does anyone want to comment on these two possibities - L2TP on the router 
versus MPLS ? Do common routers (eg. Edimax BR6204WG) support L2TP ? Is my 
ISP (HOT) likely to give me a MPLS connection without fee/hassle ? Are 
there any other solutions ?

Well if that's the case, I certainly don't want to try replace the "modem" 
supplied by HOT.
