Task
● Configure R1 ip is 192.168.1.1/24 and R2 ip 192.168.2.1/24
● Configure ASA1 on e0 ip 192.168.1.10 nameif inside and e1 ip 192.168.2.10 nameif outside
● Enable telnet with no login password on R2
● Telnet from R1 to R2
● Use Class Map, Policy Map, and service policy to change the Random sequence number.
Explanation
When you try to Telnet from R1 to R2 and ASA is between them. ASA changes the tcp sequence number and sends the packet to neighbor device. In this task we do not want ASA to change it’s sequence no.
Configuration
R1
Default route from R1 towards ASA
R2
Default route from R2 towards ASA
SW02
R2 enable Telnet
Before configuring MPf
As you can see different sequence no.
Now configure class-map, policy-map and service policy
1) create an Access-list
2) create an class-map
3) Create Policy-map
4) Create service-Policy
No you again telnet from R1 to R2 and debug ip telnet packet on Routers
R1
R2
