I'm running a WISP with wireless (802.11b) distribution based on bridged rb532 boards (4 with client dist and backbone conn, 2 with only distribution and 2 for only backbone) about and a concrete and not-very-well-supported-and-stable software for clients AAA, bandwidth throtling and so on.
Now, I'm planning a really big move to a fully-routed scenario, exclusively based on RouterOS and mentioned RB532 and a RouterOS L6 x86 computer for user-man, AAA and main router.
Most of my clients are permanent or nearly permanent connected, like an ADSL/Cable connection and a VoIP Client, but people can also buy air time using user/password and access through a captive portal.
I'm doing some lab-testings using a RB532+wifi as main router, hotspot and usermanager (in fact, everything I do is done on this RB532 for testing). I have another box to set it up as distribution node.
This was the intro to my particular scenario.
Now, I'm thinking about what to use for giving access to users (always through wifi 802.11):
- PPPoE (windows compatible, CPE compatible) for permament clients + Hotspot for casual users (captive portal). Hotspot on a "Virtual AP" interface.
- PPTP (windows compatible, only RouterOS CPE compatible) for permanent clients + Hotspot for casual users. Hotspot on "Virtual AP" interface.
- Only Hotspot for everyone. MAC Login for permanent connections + captive portal for casual. Same as current but with better software, management and BW Throtling.
PPTP+Hotspot is the worst one because there's a lack of PPTP support on about 70% of my CPEs.
I'm currently supporting about 30 clients on most populated nodes (one 2ghz-radio/node) and half of them are traffic intensive (p2p soft, you know).
What I've planned is to have each node be the hotspot (and PPP Server in case), doing client validation via RADIUS to main x86 server.
But, how Resource-hungry are Hotspot, PPPoE, or both? Which option is the better for this kind of needs?
Many thanks in advance!
