netstat -tna gives the following output (concat)
tcp 0 0 127.0.0.1:4011 0.0.0.0:* LISTEN
So I think that is saying that interface 127.0.0.1 is listening on port 4011..which is almost, i think, what I need to be happening.
I am trying to set up an email server for my website, so that oscommerce is able to send out it's emails etc, etc. My isp (comcast) blocks smtp port so to work around that I'm using a different port. Yesterday when I did a port scan of my external IP address and scanned port 4011 i got that it was open and responding, today that is not the case. So I did a netstat and the preceding output is what I got.
so i'm assuming that I cannot get to that port because my internal ip address mapped to my external ip via my router is not connect with this port 4011, so I cannot telnet to it and consequently it cannot send messages to the outside world.
Is there a way to have this port listening on a different interface (192.168.1.2 exactly)
Thank you for any help and sorry if this question is ridiculous, I'm not sure how to even form it or if this is the way to go about getting done what I need done. I'm not entirely a linux newbie but I am fairly inexperienced in this type of stuff.
By the way I'm using Postfix for email service if that is relevant.
thank you again
