FPM on IOS Router

ugot2nome

Jedi:

In my example listed below, two IOS routers (R1 Fa0/1 IP:192.168.100.1/24 <----> R2 Fa0/1 IP:192.168.200.2/24) are directly connected.

The FPM service policy is applied to R1's Fa0/1 interface in the inbound direction.

Using FPM, I am trying to drop telnet traffic sourced from R2's Fa0/1 IP to R1's Fa0/1 IP.

Using FPM, I am trying to drop ICMP traffic sourced from R2's Fa0/1 IP to R1's Fa0/1 IP; if the size is greater than 1500.

I am able to accomplish this task if I use each policy individually. When combining both requirements neither policy is coming into effect. I am unsure if it is the nature of the beast or a misconfiguration or an IOS bug. If someone can please comment/suggest alternatives, I will be glad to try it. Thanks in advance for your help.
