Discuss some of the problems NATs create for IPsec security. Can we solve these problems by using IPv6? Why deployment of IPv6 has been slow to date. What is needed to accelerate its deployment?
Before discussing the problems that NATs create for IPsec Security, I would like to mention a few details regarding NAT and IPsec. NAT or Network Address Translation allows globally registered IP addresses to be re-used or shared by several hosts (Phifer, 2000). NAT uses the rarely used source ports to accumulate supplementary information on the local computer that sends a packet.
IPsec is normally the generally ideal for VPN tunneling over the internet (Nist.gov, 2005). There are two basic protocols defined in IPsec, the primary being the Encapsulating Security Payload (ESP) and the other is the Authentication Header (AH). NAT has issues with both these protocols. Firstly if we consider Authentication Header (AH), NAT traversal itself would question the validity and useful ness of Authentication Header, as the source address of the machine is totally hidden, as I mentioned earlier in the discussion about NAT. There are also similar problems associated with the ...
This solution explores some of the problems that NATs create for IPsec security, and how these problems can be resolved in IPv6. This solution also deals with the steps needed to be taken to accelerate the deployment of IPv6.
Company Integration Process Case Project
First national banks' president congratulates you on successfully managing her network's addressing issues. She then shares the information that she's about to make an offer to buy Monroe's other banks, Metropolitan savings. She's worried that the two bank's network won't integrate easily. She isn't sire what kind of servers or workstations are used by the other bank, but the IT manager at Metropolitan savings mentioned somethings about a network that relies on the internet. He also mentioned that they use UNIX servers and Windows client. What kind can you tell First National Bank's president about integrating the two networks? What protocols would you recommend that she use or continue to use to facilitate the integration process?View Full Posting Details
