[newbie] Postfix configuration question

[Troy T. Hall]

I'm confused by the postfix documentation. I have my cable modem going to a router which is providing NAT to the server via dhcp.  My ip is provided dynamically but so far has stayed at 64.72.62.150.  The routers gateway ip is 192.168.123.254.  So does the documentation below mean that for the proxy server address I want the 192. address there or the 64. or what? ------   Proxy/NAT network addresses The proxy_interfaces parameter specifies all network addresses that the Postfix receives mail on by way of a proxy or network address translation unit. You may specify symbolic hostnames instead of network addresses. You must specify your proxy/NAT addresses when your system is a backup MX host for other domains, otherwise mail delivery loops will happen when the primary MX host is down. Examples: Default: proxy_interfaces = Host running backup MTA: proxy_interfaces = 1.2.3.4 (the proxy/NAT network address) Thanks Troy T.
