Hello all,

Can anyone explain the pros and cons of NAT and Proxy server, from a
security standpoint?  It would seem to me that NAT + a firewall would be
much more secure than relying on a proxy server, but I'm having a hard time
explaining this to management.  

Also, how many times can you NAT on a network?  Is it plausible to have
remote sites connect to a distribution router (in a private frame relay
cloud), NAT there, and then connect back to the central office and be NAT-ed
again prior to going out on the internet?  Or does something get lost in
translation?  

All replies appreciated.

Jeff
