FastDPI configuration
1. Create a file aslocal.bin (or correct this file if it already exists). The aslocal file contains those ranges of private IP addresses that are used in the provider's local network. Any of the range 64512 - 65534 is indicated for them as an autonomous system number.
vi aslocal.txt 10.0.0.0/8 64512 172.16.0.0/12 64512 192.168.0.0/16 64512 cat aslocal.txt | as2bin /etc/dpi/aslocal.bin
2. Next, create the asnum.dscp file (or modify it if it already exists). The local numbers of autonomous system should be specified in this file, so the authorization will take place for them. Typically these are autonomous systems for the gray IP addresses specified in the aslocal.bin file, plus the white IPs allocated to the provider, if these white IP addresses are used on the local network, that is, they require authorization. Authorization will be done for all the autonomous systems IP addresses marked as local in the asnum.dscp file.
vi asnum.txt 64512 local cat asnum.txt | as2dscp /etc/dpi/asnum.dscp
3. To enable authorization in /etc/dpi/fastdpi.conf:
enable_auth=1
4. Set the fastPCRF servers list:
auth_servers=127.0.0.1%lo:29002;192.168.10.5%eth1:29002
The format for specifying a single server: ip%dev:port, here ip is the server IP address, dev is the local device by wich the connection can be established.
FastDPI connects to the first available fastpcrf server from the list.
Do not forget to activate the user property store:
udr=1server
IPv6
In order to enable IPv6 addresses authorization you should activate the IPv6 support. Actually, the Stingray SG authorizes a whole subnet with a predefined prefix length (by default it equals to /64) rather than particular individual IPv6 address. For example, if there are incoming packets sent from 2001:1::1 and 2001:1::10 addresses, only one of these addresses will be subject to authorization, so the returned authorization parameters will be applied to all the addresses from 2001:1::/64 subnet.
There is no analog of the aslocal.bin file for IPv6, since there are no private addresses. You must mark the AS numbers that require authorization as local in the asnum.dscp file.
IPv6 authorization is automatically enabled if fastdpi.conf has:
ipv6=1 enable_auth=1
Starting from SSG version 8.1.4, it is possible to forcibly disable IPv6 address authorization by specifying in fastdpi.conf:
enable_auth_ipv6=0
