Sendmail Behind a NAT

[jlh1]

I have sendmail version 8.11 on a Linux box behind a router using a private ip range
I can send and receive email to local address and send external email address, now
I would like to receive email from external sources.

I use NAT ip filtering to allow other services to access internal servers from the outside.

I would like to open the ports for sendmail to be accessed thru an ipfilter on the router.

I believe that I would need to allow port 25 and 110 access thru the router to an email server
with a private ip number listening on these ports.

I'm I making this simpler than it actually is?

Thanks

I believe that should work fine - I have a similar setup.

FWIW, you won't need port 110 for sendmail. You'll only need it if you want to be able to retrieve POP3 mail from that server from the outside.

Ditto - as long as your router knows where to find the server, you're cool.
