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 _-_|\ Terry Dwyer E-Mail: tdwyer@io.telecom.com.au / \ System Administrator Phone: +61 9 491 5161 Fax: +61 9 221 2631 *_.^\_/ Telecom Australia Telstra Corporation MIME capable mailer v Perth WA ( I do not speak for Telstra or Telecom )
