Hey folks,
We have a linux box which is set up to perform NAT and is serving as a firewall for
the internal network. (ipchains set to deny everything and then a few services are
then allowed). Sendmail is forwarding incoming mail into the internal net to be
recieved by our email server. The linux box also has FTP enabled (with restrictions
such as no creating of directories) and a small Apache website which sees VERY little
traffic.
We recently had our network evaluated by several companies. one of whom suggests the
removal of the linux box. They suggest that the netopia router perform NAT. and ftp
and Web hosting put off site. (Please remember these two services are see little
traffic.)
If I do pull nat from the linux box, would I not loose the ability of sendmail to
route incoming emails?
In the past, My predeccessor, along with a local consulting firm, spent several weeks
trying to get the netopia router to do the NAT but they were unable to get the router
to perform at an exceptable level of performance.
Is there something that they or I missed?
Is this so wrong that we have to spend a bunch of time reconfiguring it?
all points of view would be appreciated.
Kind regards,
James Scott Peters
