      I'm testing the new 2.0-RC1 tonight and it looks awesome.

      But messing around with captive portal I noticed an issue with "Per-user bandwidth restriction."

      Per-user bandwidth restriction:
      @Pfsense:

      If this option is set, the captive portal will restrict each user who logs in to the specified default bandwidth. RADIUS can override the default settings. Leave empty or set to 0 for no limit.

      At first I just enter 128 for the upload and nothing for the download and save, then tried as a client and nothing works as in no connection, web pages don't load, ping get's an ip but request timeout, like the connection is blocked.
      If I set the download to 0 and upload to 128, same thing.

      If I set the download to anything else but 0, everything works fine, even speedtest shows correct bandwidth that I specified.

      Wondering if this is just a discrepancy and working as intended or a bug that needs to be fix.

        It depends.
        Its strange that you want to limit only upload?
        Not sure anyone has ever tested that path. Possibly there might be issues in code not preventing it from generating a false config.

        Can you post the ipfw pipe show and ipfw show after you enable the CP with download of 0?

          I fix computers with my dad, and sometimes we get either knowingly or unknowingly infected machine that sends out bulk mail/spam/worms/other and gets us in trouble with our service provider, but we need a network connection to access the fileserver and the pxe server. We also share the pipe with video conferencing and voip phones and our pipe is limited to 10 down 1 up. Plenty of download not enough upload.

          Captive portal on 1.2.3 works great for this, blocks the connection and leaves pinholes for fileserver and pixie and when we need to connect to the web for tools or updates, the simple authentication works fine for us, and the bandwidth limits prevents machines from hogging the upload and shares the bandwidth with other devices on the network.

          anyways…

          So here are the snippets for the command you asked for.

          I disabled CP first and then the bandwidth restriction but it didn't show anything different so I re-enabled and copy this snippet
          When I was screwing around trying to troubleshoot it and I set it to 1024 initially.
          CP bandwidth download set 5120.

          Wasn't sure if you want another pipe show or just show so I posted both.
          CP set to 0
          Now it's different.
