Marcus,
Matthew Pozzi has asked me to send you details of how we got the ISDN
Multilink connection working at VQA here in Brisbane. The following are
the parts I added to the network.conf file on the machine in question. This
was all done on a Dachstein CD Version of the Leaf Firewall. Our distribution
uses an isdn.lrp module loaded at startup to place the files for isdnctrl and
others relevant to the isdn interface.
Firstly the definition of the variables for the connection. these only
need to be defined once as the same settings apply for each chanel.
###############################################################################
# ISDN Link - the isdn.lrp is required for this to work. (External Interface)
###############################################################################
#ippp0_IPADDR=139.130.195.30 # My IP Address, only set if not dynamic.
#ippp0_PTPADDR=139.130.195.1 # Their IP Address, again only if not dynamic.
#ippp0_MYMSN=38049800 # My telephone Number
#ippp0_REMMSN=30073300 # Their telephone number (The ISP)
#ippp0_IP_SPOOF=YES
#ippp0_IP_KRNL_LOGMARTIANS=NO
# Simple QOS support, Options are same as ethernet above.
#ippp0_FAIRQ=YES
#ippp0_TXQLEN=64
#ippp0_BNDWIDTH=64kbit # Device Bandwidth
#ippp0_HNHL=3 # Queue Handle - must be unique
#ippp0_IABURST=25 # Interactive Burst
#ippp0_IARATE=30Kbit # Interactive Rate
#ippp0_PXMTU=1500 # Physical MTU - includes Link Layer Header
You probably have these already but I put them in for completeness. Next we
added to the Interface activation/deactivation functions as follows:
First pull out the relevant connection parameters ( not sure if I added to the
standard Dachstein here or not)
if_up () {
local ADDR
# sort out a few things to make life easier - here so that you
# can see what is done and so that you can add anything if needed
eval local IPADDR=\${"$1"_IPADDR:-""} # I am also a good genius
eval local MASKLEN=\${"$1"_MASKLEN:-""}
eval local BROADCAST=\${"$1"_BROADCAST:-""}
eval local MYMSN=\${"$1"_MYMSN:-""}
eval local REMMSN=\${"$1"_REMMSN:-""}
eval local PTPADDR=\${"$1"_PTPADDR:-""}
eval local PXMTU=\${"$1"_PXMTU:-""}
eval local DEFAULT_GW=\${"$1"_DEFAULT_GW:-""}
eval local IP_EXTRA_ADDRS=\${"$1"_IP_EXTRA_ADDRS:-""}
eval local ROUTES=\${"$1"_ROUTES:-""}
eval local FAIRQ=\${"$1"_FAIRQ:-""}
eval local TXQLEN=\${"$1"_TXQLEN:-""}
eval local IP_SPOOF=\${"$1"_IP_SPOOF:-""}
eval local IP_KRNL_LOGMARTIANS=\${"$1"_IP_KRNL_LOGMARTIANS:-""}
eval local IP_SHARED_MEDIA=\${"$1"_IP_SHARED_MEDIA:-""}
eval local BRIDGE=\${"$1"_BRIDGE:-""}
eval local PROXY_ARP=\${"$1"_PROXY_ARP:-""}
if [ -n "$BROADCAST" ] ; then
IFCFG_BROADCAST="broadcast $BROADCAST"
fi
Then the interface activation section
ippp*)
# Get ppp user
USER=`cat /etc/ppp/pap-secrets | grep ^[a-zA-Z0-9] | sed 's/\*.*//'`
# Set up the ISDN interface
isdnctrl verbose 3 #>/dev/null

if [ -z "$IPADDR" ] ; then
echo 1 >/proc/sys/net/ipv4/ip_dynaddr
ip link set $1 dynamic on
else
ip addr add $IPADDR peer $PTPADDR dev $1
fi
ip link set $1 arp off multicast off
ip link set $1 up
if [ -z "$IPADDR" ] ; then
/usr/sbin/ipppd mru 1500 mtu $PXMTU ipcp-accept-local
ipcp-accept-remote lcp-restart 1 name $USER noipdefault +mp /dev/$1 /dev/ippp1 &
else
/usr/sbin/ipppd mru 1500 mtu $PXMTU lcp-restart 1 name $USER
$IPADDR:$PTPADDR +mp /dev/$1 /dev/ippp1 &
fi
ip route add default dev $1
# Fair queuing - this can be selected for any interface
ip_frQoS $1
;;
if_down () {
ippp*)
/usr/bin/isdnctrl hangup $1
sleep 1

Hope this helps you to get the configuration you need working.

Markus, have not heard from my friend, but will chase him up. I found the
answer to mppp on google, so it is out there, but I have not got the
firewall access so I will have to chase him up. Yes we use a similar ISDN
system to you, Australia used the European system not the US one.
Thankfully.
Yes we used the hisax modules to, I will try and get those files for you
soon, please stay in touch.
Matthew
