## Gaming service

### Configure pppoes
/etc/api.conf 
```
apikey=SecretTokenRandom
allowip=10.168.100.
```
allowip must be set to ip of your nat

### Configure radius
Configure for gaming service radius attribute "Login-LAT-Service" with value "gaming"

### Configure nat
* Run several instances of pppoe gaming pollers that will retrieve list of gaming users
```
gamingclient  -u http://pppoeip:apiport/ -k SecretTokenRandom 
```
apiport by default 9000, might be different in some cases

* Configure ipset for gaming users
```
ipset create gamingclients hash:net timeout 120
```
Also add relevant rules to nat users to different pool, for example:
```
iptables -t nat -A POSTROUTING -m set --match-set gamingclients src -j SNAT --to-source $GAMING --persistent
```
where $GAMING is ip of your gaming pool (1.2.3.1-1.2.3.10 for example)

### How it works?
* User login and get gaming service attribute from radius
* API daemon will detect such user and put in special list available over API HTTP GET request
* Gaming poller will retrieve list of users and put them in ipset each X seconds
* NAT will detect users in ipset and will put them in gaming pool
* If user will be disconnected, gaming poller will not readd user, and it will be removed from ipset after 120 seconds by ipset timeout
