Are you aware that if your SMTP server is on an IP in the range of
addresses your ISP doles out to its private customers, you may be on a
blacklist of IPs to ignore.  It's a common practice for many other mail
servers, or their incoming mail filters, to only accept mail sent from
ISP mail servers, and other large networks.

A few years back my ISP increased the number of IPs that they use
(dynamically allocated to their customers).  And, apparently, there's
still a problem with us using those newer IPs, as many other services
don't have them in their database of acceptable IPs.

Can't you get a better one?

If not, can you set it up in bridge mode?  Then you can use it as a
simple modem, and the completely configurable computer as the router.
