Local users are a feature of ddwrt and it has nothing to do with chillispot. You should ask this in ddwrt forums.

Hello,

it has to be set in the radreply table. But you have to calculate the time that the user spent online and update the Session-Timeout attribute by deducting the online time from it, otherwise the user will have the same amount of time when logging in again.

Hello,

yes it's possible.

The first router has to be configured as a hotspot router and you must set the LAN ports to have 'chillispot enabled' ports.
We're using HotSpotSystem.com as the hotspot provider but you can make it work with others too.

Here's how you can set the LAN ports to have chillispot enabled ports:

1. Setup > Basic setup > Network Address Server Settings (DHCP)   > DISABLE (then Save)

2. Administration > HotSpot > Seperate WiFi from The Land Bridge > DISABLE, and
    Administration > HotSpot > DHCP Interface > Set  LAN & WLAN (then Save)

Then you must configure WDS for the 2 other routers (you don't need to have chillispot running there). Once they're connected they will get IP addresses by the chillispot from the parent router.

To configure WDS you can read this article:

If you're using a centralized hotspot system you can have 3 routers, all running chillispot with 3 SSIDs so users can choose where to connect.

Well, the manual = documentation...

You can find more information in the FAQ... if you have questions, just ask it here.

What's exactly that you're trying to do?

The problem is that paypal.com is using different and multiple IP addresses and when chilli resolves the ip address of paypal.com, which has multiple IPs, only the first one will be allowed which may lead to unexpected results...
