NAT offer wider covering of protocols but for a common (which is supported by proxy & NAT both)protocol Proxy is always secure than NAT that is what explained in this article. please correct me if you still think that i am wrongSantosh Kumarhttp://www.blogger.com/profile/02513808523793512917noreply@blogger.comtag:blogger.com,1999:blog-3482544788258502726.post-49102718897541110662013-07-14T13:00:16.512+05:302013-07-14T13:00:16.512+05:30Not fully agreed, yes proxy is secure as it provid...Not fully agreed, yes proxy is secure as it provide protection up to 7th layer of OSI,<br><br>But it has some constraints - it is restricted to some ports or service only- can not be used widely for anything, on the other hand - NAT is some thing which is used to translate - Source /Destination / Ports . It works on all the services/ports - for example telnet/ssh/IPSEC VPN.<br><br>In other words - Proxy and NAT has their own functionality - and can be deployed according to requirement/budget only.<br><br>There are multiple devices - which provides solution differently, so in the end all comes to your company infrastructure and budget only.<br><br>Good Luck :)Harinderjeet Singhhttp://www.blogger.com/profile/18051765767905068505noreply@blogger.com
