• Internal Network 172.16.32.0 / 255.255.255.0
• Default gateway is 172.16.32.1
• 192.168.1.1/24 is the serial interface on my 1721 router
• 192.168.2.2/24 are the IP’s provided by my ISP.
• Ethernet IP of my firewall (ouside Interface) is 192.168.2.2/24
• Other Service Provided’s IP are 10.10.10.1/24
• In my firewall I have nated my private IP to public interface of firewall.
• This configuration works well with out redundancy. All Traffic from my
private network is routed to VSNL..
I have to now build redundancy such that if VSNL Link fails all traffic is
Diverted to SIFY.
I have configured cisco 2801 ethernet interface to have valid ip provided
By VSNL so that I can build HSRP.
Cisco 2801 is coming active if VSNL circuit fails but my internet traffic is
No reaching Internet.
