I have two NIC's, bge0 with a public IP and vr0 which I've assigned the
private ip 10.42.73.37/8 which I sucked out my thumb.
I'm using the standard pppoe startup script and this is in my
pppoed_flags="-d -P /var/run/pppoed.pid -a yonetwork -l default"
The contents of my /etc/ppp/ppp.conf are:
set log Chat Command Phase
allow mode direct
set mru 1472
set mtu 1472
set ifaddr 10.42.73.38 10.42.73.37
set radius /etc/radius.conf
The contents of /etc/radius.conf are:
auth radiusmachine:1812 "my_secret"
acct radiusmachine:1813 "my_secret"
That is all the configuration that I have for the PPPoE setup.
I have configured the machine as a gateway and there is no firewall
running on the box at the moment. It plugs into a switch and I'm
statically routing the netblocks that my clients use to the bge
interface of the box.
All the clients use public IPs. Here is a snippet of the output of
tun26: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1492
inet 10.42.73.38 --> xxx.xxx.xxx.26 netmask 0xffffffff
Opened by PID 490
tun27: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1492
inet 10.42.73.38 --> xxx.xxx.xxx.13 netmask 0xffffffff
Opened by PID 754
tun28: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1492
inet 10.42.73.38 --> xxx.xxx.xxx.7 netmask 0xffffffff
Opened by PID 563
The problem is that the machine will not take more than 30 clients. I'm
trying to find a limit somewhere in the config files but I can't. The
kernel has NETGRAPH, NETGRAPH_PPP and NETGRAPH_PPPOE in it.
