I am using FreeBSD 2.2.8-RELEASE as my PPP server. When a client dials
in, the ppp0 device looks like this:
ws70:~> ifconfig ppp0
ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
inet6 fe80:9::280:c8ff:fe4c:67b8 prefixlen 64
inet xxx.xxx.xxx.70 --> xxx.xxx.xxx.101 netmask 0xffffffc0
ws70:~>
So the server side report the correct netmask (255.255.255.192). At
the same time, on my home PC (FreeBSD 3.1-RELEASE) I have a wrong
netmask (255.255.255.0) as shown in the following output:
morse:~> ifconfig tun0
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
inet xxx.xxx.xxx.101 --> xxx.xxx.xxx.70 netmask 0xffffff00
morse:~>
I have read the docs but it seems like I haven't read carefully
enough :-) Do you have any idea how to tell the client the correct
netmask (I'm too lazy to write "ifconfig tun0 netmask 255.255.255.192"
every time :-). Below are the config files on the server.
/Martti
/etc/ppp/options
================
crtscts # use hardware flow control
modem # use modem control lines
passive # wait for LCP
+pap # use PAP
login # use /etc/passwd with PAP/CHAP
auth # require auth. before allowing packets
domain my.name.com # our domain
netmask 255.255.255.0 # netmask
proxyarp # clients' ARP addresses point to this host
ms-dns xxx.xxx.xxx.xxx # tell DNS server address to Windows clients
/etc/ppp/options.ttyd0
======================
xxx.xxx.xxx.70:xxx.xxx.xxx.101
