Can't access Unity Express (CUE) from LAN

I'm trying to deploy CUE 8.6 on a 2921 with a ISM-SRE-300-K9 module and CME 9.1

I can start a session to CUE and ping it from the router with no issues, but I can't reach it from LAN either via web or ping, I can ping the router's loopback IP with no problems.

When I traceroute from LAN it goes out the Internet interface since it's the default route even though I have configured a specific static route for the module, when I try the same traceroute to the router's IP it reached with no problem.

Current config: 

interface Loopback1
ip address


interface ISM0/0
 ip unnumbered Loopback1
 service-module ip address
 !Application: CUE Running on ISM
 service-module ip default-gateway


ip route ISM0/0


Trace to router from LAN:

traceroute to (, 30 hops max, 60 byte packets
1 gateway ( 4.947 ms 4.947 ms 5.077 ms
2 ( 0.691 ms * *

Trace to module from LAN:

traceroute to (, 30 hops max, 60 byte packets
1 gateway ( 2.263 ms 2.379 ms 2.594 ms
2 ( 2.642 ms 2.658 ms 2.715 ms ( 2.053 ms 2.136 ms 2.149 ms  <-- ISP Default GW

I have tried with ip unnumbered and also with explicit IP on the ism0/0 with the same results

I have also restored the module to factory settings with the same results.

Seems that does

Seems that does not have a route to Does it have a static route to Or does it have a route to

Yes as in my original post

Yes as in my original post there's a static route 

ip route ISM0/0

also is my loopback

Loopback1 YES manual up up

from I can ping both addresses

You can ping

You can ping from from your trace route that this device is sending traffic for out its default gateway. Can you post the routing config from this device?

New Member

Yes, I can ping

Yes, I can ping from, from LAN I can ping but not it sends the traffic through my default route even though I have a static route for the module:

#show run | i ip route
ip route track 20
ip route 2
ip route ISM0/0

ping from

The traffic goes out my default internet gateway

The ip route command "ip route ISM0/0" should only be on not on Not sure which device the show run command above is from.


New Member and and are the same device, the first is the LAN address and the second is a loopback created for the CUE, basically it's just my PC directly connected to the router with the ism module, still it goes out the wan interface instead of following the static route
