ACCESS LIST IN GNS3 WITH VMWARE

Access list used for filtering IP traffic, defining traffic to network address translate

(NAT).

In this scenario i am giving only remote access permission (RDP) from XP1 (192.168.10.10) to XP2(192.168.20.10).remaining all traffic from XP1 to XP2 well be bloking.

SSH into Gns3

How to SSH into Gns3 Router from vmware machine

In this scenario explaining how to ssh from Vmware machine to gns3 router. The router R1 is C2600 and Cloud C1 is used for connecting vmware machine to gns3 with vm virtual adpter VMnet1(host only).The IP address of the router interface is 192.168.10.1 and vm interface is 192.168.10.10

Configuration Router R1

R1#conf t

R1(config)#int fa 0/0

R1(config-if)#ip address 192.168.10.1 255.255.255.0

R1(config-if)#no sh

R1(config-if)#exit

R1(config)#enable secret cisco

R1(config)#username admin password cisco

R1(config)#crypto key generate rsa

The name for the keys will be: R1.red.com

Choose the size of the key modulus in the range of 360 to 2048 for your

  General Purpose Keys. Choosing a key modulus greater than 512 may take

  a few minutes.

How many bits in the modulus [512]: 1024
