I'm trying to configure a system like this:
Linux gateway/router: 10.2.1.1
CE150 DSLAM: 10.2.1.5 and 10.2.200.2 (the second IP is the port that the SDSL Modem syncs with)
Netopia 7100 SDSL Modem behind the DSLAM: 10.2.200.1 and 10.2.200.3 (external and internal IP's)
I need help making this work.
The linux box can ping the DSLAM. The Netopia can ping the DSLAM. Traffic will NOT get passed from the Netopia to the Linux gateway -- the farthest I can ping is the DSLAM. In other words, traffic can get to the DSLAM from either side (external = linux box, internal = SDSL modem), but no traffic seems to get THROUGH the DSLAM.
Here's the confg on the DSLAM:
System(1.3)> get cmif [1.4.20]
PII = 22.214.171.124
IfIndex = 126.96.36.199
Name = RJ45-TEST
GroupName = ""
AdditionalInfo = ""
NetModel = IP
IpAddr = 10.2.200.2
NetMask = 255.255.255.0
MacAddr = ff.ff.ff.ff.ff.ff
BurnedInMacAddr = 0.0.c188.8.131.52
FarEndAddr = 10.2.1.1
DestPII = 184.108.40.206
CMCPCompatible = Yes
EncapsulationType = rfc1483
FwdMode = IP-Policy
Pix = 22
ServiceClass = D
Here's the configs on the Linux Gateway (eth2 is a live external ip -- I changed it here for privacy):
[zberke@gateway zberke]$ /sbin/route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.200 * 255.255.255.240 U 0 0 0 eth2
10.2.0.0 * 255.255.0.0 U 0 0 0 eth1
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default gw.switc 0.0.0.0 UG 0 0 0 eth2
[zberke@gateway network-scripts]$ more ifcfg-eth1
[zberke@gateway network-scripts]$ more ifcfg-eth2
I don't have the config for the DSL Modem in front of me, but I can get it ASAP if this info is not sufficient. I think it's a problem with the DSLAM config (since traffic is not getting passed) or possibly with the linux routing tables, but I'm not sure.
Thanks in advance for any and all help.
