Hello
I am trying to deploy an AIM-IPS inside a 2811 rtr. The module is seen by the rtr and I can log into the AIM-IPS module.
I have followed Cisco recommendation by NOT giving the inside interface an addfress and have used ip unnumbered.
The AIM-IPS is bound to the same subnet and interface that the internal address
Anyone have any suggestions?
Any tips for a successful deployment?
Below are the config details from the rtr and AIM-IPS
cheers

You have access-lists applied to your GigabitEthernet0/3/0.1.
Do you have traffic to/from the sensor's 192.168.200.99 address permited in these access lists?

hello:
i had nothing in the access lists that would deny traffic to/from the same subnet
I have since added a specific rule for the AIM-IPS evice , still no differance (;
I added thi sto the interface to ensure inter Vlan traffic on the one ar,m router would work
no ip split-horizon
this did not have any affect w.r.t. to AIM-IPS
I need to be able to upload the license file so that i can first update the signature
any other suggestions

update:
I was NEVER able to get this to work on a "one arm router" regardless of which vlans I used.
I sent a note to my Cisco SE as to why inter-vlan routing does not work on 2800 & 3800 series ISR router with traffic between vlans that share the same physical link. Anyone ever get this to work?
I had a spare unused L3 physical i/f on the isr router, so i tried this long shot.
VOILA, the aim is is now working
service modules summary
anyone else gets this to work without using a seperate i/f?
if so, how and which platform?
