I have kernel ppp (pppd) running between two machines quite happily, but
dont have proxying working.
Server machine: FreeBSD io 2.1.6-RELEASE
Client machine: FreeBSD charon 2.1.5-RELEASE
The Kernel config includes ARP_PROXYALL on both machines and
gateway="YES" is set in /etc/sysconfig.
I have aliases bound to the ed0 interfaces on both machines if it
matters.
--- /etc/ppp/options --- this is identical for both machines ----
crtscts # Hardware flow control
domain [dummyname].com.au # My domain
passive # Wait for LCP
modem # use modem line
proxyarp # Use ARP proxy routing
netmask 255.255.255.192 # set the netmask for the ppp link
lock # use UUCP style lock
debug # Increase dubugging level
#+pap # enable PAP authentication
defaultroute # Add a default route to kernel routing table
mtu 552 # Better interactive performance
----------------------------
I dial the server using a script, this is the relevent section for pppd:
/usr/sbin/pppd $DEBUG $OPTIONS -detach modem defaultroute proxyarp \
crtscts $NETMASK $DEVICE $DEVICESPEED
The variables are supplied from a conf file or from within the script.
These are the parameters supplied to pppd:
Phone: 4444444, User: [pppusername], Password: [dummypasswd]
Our ip addr: [null], Their ip addr: [null], Netmask: 255.255.255.192
PPP options:
Addresses are negotiated with the server.
When pppd connects to the server, the IP addresses from options.cuaax
are negotiated properly, then I see this entry in the pppd log files on
both machines:
Cannot determine ethernet address for proxy ARP
If I try manually adding an arp entry it is also unsucsessful.
arp -s ppplink 00:00:c0:51:cd:40 pub
cannot intuit interface index and type for ppplink
Can anyone give me a pointer as to why proxying won't work
