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.

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?
