PPPoE server: Revision 8
{toc: }
Here are my notes how to configure pppoe-server to run as server for ADSL modem. ^ Prerequisits This list might be incomplete .pre apt-get install pppoe .pre ^ PPP configuration ^^ /etc/ppp/pppoe-server-options .pre # PPPoE server #nologin mru 1492 noreplacedefaultroute proxyarp ms-dns 192.168.1.1 .pre ^^ /etc/ppp/pap-secrets .pre # PPPoE server #client hostname <password> IP test * "test" * .pre ^^ /etc/ppp/chap-secrets .pre # client server secret IP addresses test * test * .pre ^ Configuration We will have fake network `10.0.0.0` on IP alias `eth0:1` and will give out addresses in that range. While we could go with just one network, this is more clean, since we will see difference in packets traveling over PPP link as opposed to direct connection. .pre ifconfig eth0 192.168.1.90 up ifconfig eth0:1 10.0.0.1 up .pre ^^ PADI .pre pppoe-relay -B eth0:1 -C eth0 -n 1 -F .pre ^^ PPPoE .pre pppoe-server -I eth0:1 -T 60 -C fake -S fake -L 10.0.0.2 -R 10.0.0.10 -N 1 -F .pre ^^ NAT .pre iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -j SNAT --to-source 192.168.1.90 .pre ^ Debugging To sniff all traffic expect web (I guess that most ADSL modems have web interface) use something like: .pre tshark -i eth0 -f '!port 80' .pre |
