Which is better PPPOE / PPTP / L2TP for CPE

I’m looking for advice and other peoples experience with the mentioned client connection methods over Wireless. I am about too launch a WISP in my area and am confused as to the preferred method for client conectivity to my AP’s. My backend uses ( MT router boxes ).

I have been testing with PPPOE and PPTP and have found various reliability issues with both. I have found PPPOE to be the most reliable method over marginal quality links. I am after other peoples thought and experiences as I want too do it right and not have to change my clients half way thru. I have found that PPPOE only works with certain CPE’s, whereas PPTP works with all. If PPPOE seems to be the preffered method
then I will be using SMartBridge CPE’s. I have settled on AirPoint Total for my AP’s.

I appreciate any feedback or experience.

hello.
it depends, of course, from your network design.
for PPPoE a layer 2 connection to the access concentrator (AC) is necessary, for PPTP a routed on.
in germany every DSL-router is PPPoE capable, most PPTP.
only newer operating systems integrate a PPPoE driver, and e.g. MacOS X cant bind it to the wlan-interface
i dont think L2TP is a choice here, as afaik only PPP type connections could be managed through RADIUS.

if MikroTik-based APs are used, it would be possible to have EoIP tunnels to the AC, therefore using standard PPPoE clients/routers. there would be no (un-encrypted) customer traffic on the wireless backbone.

If therse a routed backbone anyway, PPTP tunnels might be the better choice.

we found them both reliable enough. probably PPPoE /EoIP will result in a higher cpu-load.

i guess this is more a general networking problem, than a wireless on.

if my understand is good:

pppoe doesn’t provided cripted tunnel;

pptp can be encrypted.

Is it right?

Both PPPoE and PPtP can both be encrypted. Encryption will reduce the bandwidth.

PPPoE does work on Mac OSX WLAN (Airport) you just need this script:

The advantage of PPPoE is that you only need supply the user with a username/password combination. PPtP requires username password and endpoint IP address.

AP and CPE from http://www.osbridge.com/support.html can pass PPPoE without any problems and are cheaper than smartBridges.
