Title: Port Fowarding
Post by: Agent86 on March 20, 2006, 03:44:59 AM

Hi all

Having fun so far

Anyhow please post the typical port fowarding for the default services in the SME server

Such as webserver,mail,ftp,

And please adise on weather it's typical to put the ports in the source and destination, or to follow the suggestion on that screen to only put in the source ???


This same screen mentions something about:
The destination port may be left blank, which will instruct the firewall to leave the source port unaltered.

So this mentions firewall, and how do I know ???

I do not see anything in the setup manager about firewalls ?

Does my SME have firewall ?

I assume yes, since many use with a switch and not router etc. ??


Please advise on both thanks

You don't need to forward those ports unless your webserver, mailserver or ftp are somewhere else on your network other than on the SME server.

However, if you have a router before the SME then you need to create portforward rules in the router to forward those services to the SME server, or create a DMZ in the router (if it supports it) and point that at the SME server but only if the SME is in server/gateway mode.

This is all a moot point anyway because from your previous posting it appears that you are using comcast.net as your ISP and they block incoming HTTP (port 80), incoming FTP (port 21) and they block outgoing SMTP (port 25) to any mail server other than their own. In other words, they don't want you running servers on their residential services.

I suggest you talk to comcast but I would suspect that you will be better off changing ISP's.

Title: Perhaps your right

Thanks for the info,

Perhaps your right, I may need to get another ISP, or ask them for their commercial server with static ip or something.

So comcast blocking those ports, and so what is the general pros and cons of using other ports , I guess I'm asking can SME servup using different ports ? or just not worth it ??

And will using other port work with comcast ?

Thanks for the help, and at least it's nice to know that I may have been trying the correct fixes, but just being blocked, that helps alot.

I'm still enjoying learning about all this, as long as It has some structure to what I'm learning about, or at least learning about topics that are directly related to what I'm trying to accomplish even if it does not work at least now I'm getting better understanding about what to try and why things do not work, or why I'm even trying them to begin with.

Thanks again,

Are there no other recommendations, I'll changes ISP's if I have too, but it does work so well, for browsing etc. and all else??
