I would like to ask how I can configure my cisco 877 adsl router to have multiple firewalls installed in parallel behind the cisco 877 router. I have enclosed a diagram of what I am trying to achieve. I have a multiple public IP's and I wish to assign a public ip to the cisco 877 router and each firewall behind the router. Each firewall is from a different vendor and is being used for training purposes.
- ISP Gateway IP >> Cisco 877 Public IP 1 >> FW1 Public IP 2 >> FW1 LAN IP Subnet 1
- ISP Gateway IP >> Cisco 877 Public IP 1 >> FW2 Public IP 3 >> FW2 LAN IP Subnet 2
- ISP Gateway IP >> Cisco 877 Public IP 1 >> FW3 Public IP 4 >> FW3 LAN IP Subnet 3
I have a diagram but could not include as it is my first post.
My aims are to:
- Manage the 877 router from Network 1 only using secure protocols i.e. ssh and https
- Nat performed by each firewall
- Create a SSL/IPSEC VPN to each firewall for testing.
Many thanks for your help
