Schneibster Posted December 10, 2004 Share Posted December 10, 2004 I report spam from two addresses, and they are both behind NAT firewalls. When I set up in the Mailhosts application, it groks my internal hostnames, which are simply the internal hostname.internal.mydomain.com. This hostname cannot be looked up on the open 'Net, for security reasons- not to mention I am using the internal IP addresses for them both, 192.168.x.x, so it wouldn't do any good to look it up anyway, and even if you could, the NAT wouldn't pass it. The NAT, of course, turns it into the real IP address of the NAT firewall's Internet connection. Mailhost does correctly grok those real IP addresses. On edit: Just for clarity, my firewall is a NAT only, with port triggering/port forwarding. It does not do SPI, nor does it change anything but the port and IP address in the IP header. Is this correct? Will this work properly? Thanks! -Da Schneib Link to comment Share on other sites More sharing options...
