I am new to CISCO!
I currently use MS ISA Server 2006 to protect a windows internal network, where there is also an MS Exchange server. I have acquired a Cisco 5510 to enhance security at main office. Later I will have ASA 5505 for branches, including VPN-ning. Please help in:
- to have firewall at main office. I have several public IPs and would like to setup DMZ for Web, Exchange server and FTP. How do I setup interface and sub-interface for the DMZ?
- Can I continue using ISA Server connecting to Cisco 5510 on the perimeter? If so, How do I set the interfaces (and sub-interfaces) as well as NAT-ting and access configuration between the inside and outside?
I will appreciate some sample code lines.
