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 192.168.11.1 255.255.255.252
end

!

interface ISM0/0
 ip unnumbered Loopback1
 service-module ip address 192.168.11.2 255.255.255.252
 !Application: CUE Running on ISM
 service-module ip default-gateway 192.168.11.1
end

!

ip route 192.168.11.2 255.255.255.255 ISM0/0

!

Trace to router from LAN:

traceroute to 192.168.11.1 (192.168.11.1), 30 hops max, 60 byte packets
1 gateway (172.30.21.1) 4.947 ms 4.947 ms 5.077 ms
2 172.30.22.1 (172.30.22.1) 0.691 ms * *

Trace to module from LAN:

traceroute to 192.168.11.2 (192.168.11.2), 30 hops max, 60 byte packets
1 gateway (172.30.21.1) 2.263 ms 2.379 ms 2.594 ms
2 172.30.22.1 (172.30.22.1) 2.642 ms 2.658 ms 2.715 ms
190.128.192.117 (190.128.192.117) 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 172.30.22.1 does not have a route to 192.168.11.2. Does it have a static route to 192.168.11.1? Or does it have a route to 192.168.11.0/24?

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


ip route 192.168.11.2 255.255.255.255 ISM0/0



also 192.168.11.1 is my loopback


Loopback1 192.168.11.1 YES manual up up


from 172.30.22.1 I can ping both addresses

You can ping 192.168.11.2 from 172.30.22.1?Seems from your trace route that this device is sending traffic for 192.168.11.2 out its default gateway. Can you post the routing config from this device?

Yes, I can ping 192.168.11.2 from 172.30.22.1, from LAN I can ping 192.168.11.1 but not 192.168.11.2 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 0.0.0.0 0.0.0.0 190.104.170.133 track 20

ip route 192.168.11.2 255.255.255.255 ISM0/0

The ip route command "ip route 192.168.11.2 255.255.255.255 ISM0/0" should only be on 192.168.11.1 not on 172.30.22.1. Not sure which device the show run command above is from.

172.30.22.1 and 192.168.11.1 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

Is CME' gui file uploaded on router's flash ? Are you able to browse CME ?
