Hi Team.

I have GNS3 installed on windows 7. A Router R1 is connected to cloud. Cloud is connected to MS Loopback Adapter. ICS is configured so that Loopback can communicate to internet.

Further I configured a Router R1 which is now reaching the internet.

Now, I have configured a GRE tunnel.

interface Tunnel0
description Z
ip address 172.18.150.177 255.255.255.252
ip virtual-reassembly
keepalive 5 3
tunnel source FastEthernet0/1
tunnel destination 114.112.231.106

However tunnel is not coming up. What I observe is the GRE traffic is not going to internet from my windows box.

Router#sh int tun0
Tunnel0 is up, line protocol is down
Hardware is Tunnel
Description: Z
Internet address is 172.18.150.177/30
MTU 1514 bytes, BW 9 Kbit, DLY 500000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation TUNNEL, loopback not set
Keepalive set (5 sec), retries 3
Tunnel source 192.168.137.2 (FastEthernet0/1), destination 114.112.231.106
Tunnel protocol/transport GRE/IP
Key disabled, sequencing disabled
Checksumming of packets disabled
Tunnel TTL 255
Fast tunneling enabled
Tunnel transmit bandwidth 8000 (kbps)
Tunnel receive bandwidth 8000 (kbps)
Last input 01:33:55, output 00:00:03, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue: 0/0 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec

R1[192.168.137.2]--->MS-Loopback Adapter: [192.168.137.1] --> Windows 7 with ICS [192.168.1.101] --> DSL [192.168.1.1]--> internet

Traffic is seen on the loop back adapter but is not handed over to 192.168.1.101
Images Attached:

What I am trying to achieve is configure a GRE on GNS3 Cisco Router to connect to a tunnel over internet. Where GNS3 is installed on Windows 7
Please suggest
