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. > So what you > need is an Ethernet router (with an Ethernet port on his WAN port). 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. > > Then I would suggest that you ditch the "dialing" part of the loop.

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 ?

Well if that's the case, I certainly don't want to try replace the "modem" supplied by HOT. > > My 7.4 agorot, > Thanks - worth at least 7.4 agorot ! > -- Shimi > > On 10/8/09, Aharon Schkolnik <aschkol...@gmail.com> wrote: > > Hi. > > > > I am currently connected to the Internet via a HOT cable connection > > using the modem supplied by them and a single ethernet connection to > > my PC.
