Our MS Proxy 2.0 Server is sitting between our Internet router and our internal router. It appears that the proxy server is performing NAT and HTTP proxy services. How do we ascertain whether the proxy server is performing NAT, since we are not that familiar with the MS Proxy server?
We are going to put the firewall into the network behind the Internet router, but in front of the MS Proxy server with the proxy on the inside interface. Should we let the MS Proxy continue to perform NAT? If not, what are your reccommendations. Also, what would be the best way to implement this solution quickly?
Last but not least, there are three networks to route to on the inside interface of the firewall, however, two of the networks will not have inbound traffic initiated to devices sitting on the networks, but the third network will have traffic initiated inbound to devices. Can you please make reccommendation(s) on how to handle this?
