Telnet to a 1841 from another source address

[Daravae]

Hey everyone,

Practicing extended numbered ACL's for my upcoming CCNA through this lab:
Lab 38: Configuring and Applying Extended Numbered ACLs Inbound (itexamanswers.net)

I have two 1841 routers connected over a single serial connection.
R1 interface 172.16.1.1/26
R3 interface 172.16.1.2/26

I have configured 3 loopback interfaces on R3:
Loopback10: 10.10.10.3/25
Loopback20: 10.20.20.3/28
Loopback30: 10.30.30.3/29

I configured Telnet on both R1 and R3 and configured an extended ACL on R1 to explicitly permit Telnet from R3 Loopback10 and Loopback30, deny telnet from R3 Loopback20 but allow ping traffic from R3 Loopback 20.

However, I'm using Packet Tracer for my labs. How can I telnet to R1 from R3 using the source address from Loopback20? 
Below command does not seem to work on a 1841 in Packet Tracer:

telnet 172.16.1.1 /source-interface loopback20 

 Responses are appreciated.

what is the error you getting ? Hope you have VTY Lines configured to send telnet from device out.

Hi Balaji,

Below error:

I've set the VTY lines. Here are the running-configs of both routers: Config - Pastebin.com

[balaji.bandi]

what is the options you have  in each command ? (that give you information) #telnet x.x.x.x ?

make sure using Loopbackxx you can reach outside network.

also consider using below option :

ip telnet source-interface

To specify the IP address of an interface as the source address for Telnet connections, use the ip telnet source-interface command in global configuration mode. To reset the source address to the default for each connection, use the no form of this command.

ip telnet source-interface interface

[Daravae]

These are the options I have.

I have static routes from R1 to R3 for all loopback interfaces. Please take a look at my running-config above.

There does not seem to be an option ip telnet source-interface interface available. Neither in priv. exec or global config mode.

Is this just simply not possible in Packet-Tracer? Do I need to use GNS3 if I want to use source-interface for telnet ?

[Daravae]

Starting to suspect this might just not be supported in Packet-Tracer. 

It is available on my Cisco CBS250:
