[Asterisk-Users] hdlc setup routing question

[Vasyl Rublyov]

Michael,

I see that you configurataion is FR, and your router (with t100p) should 
have 209.26.250.74 and P2P end shoud be 209.26.250.74.
Usually they are both belongs to ISP (in this case to Sprint), but your 
Ethernet end is 209.26.224.34/29.

Hope this will work for you;

MODE=fr
LOCAL_IPADDR=209.26.250.74
REMOTE_IPADDR=209.26.250.73
NETWORK=209.26.250.72
NETMASK=255.255.255.252
GATEWAY=209.26.250.73

# FR
FR_LMI=ansi
FR_PVC=pvc0
FR_DLC=44

/sbin/modprobe zaptel
/sbin/modprobe wct1xxp
/sbin/modprobe hdlc
/sbin/ztcfg -vvv

sethdlc-1.15 ${DEVICE} ${MODE} lmi ${FR_LMI}
sethdlc ${DEVICE} create ${FR_DLC}
ifconfig ${DEVICE} up
ifconfig ${FR_PVC} ${LOCAL_IPADDR} pointopoint ${REMOTE_IPADDR}
route add -net ${NETWORK} netmask ${NETMASK} ${FR_PVC}
route add default gw ${GATEWAY} metric 1 ${FR_PVC}

# 209.26.224.33 belongs to your eth0 device.
ifconfig eth0 209.26.224.33 netmask 255.255.255.248
route add -net 209.26.224.32 netmask 255.255.255.248 dev eth0

=== /etc/zaptel.conf should be like this:
loadzone = us
defaultzone=us

span=1,1,0,esf,b8zs

nethdlc=21-24
.....

also check /proc/sys/net/ipv4/ip_forward - it should be 1
