Multiple routing of a router!!!

Posted on 2004-11-03

I have paid for a dns server company which is routing all domain traffic to my adsl router (clever method as it is a dynamic ip address, works well !!! ""), which allows http, ftp , pop3 ,smtp traffic in...
One computer has the web based stuff (Websites etc...) (using sambar)
I have another computer which deals with the mail....
This is easy to set up with my router as I route the portsto the appropriate LAN ip address...
HOWEVER, the mail server also has WebMail which I want to allow people to use externally.
How can I get the router to allow traffic to enter to both!!! or even better.. allow it to enter in to the web based server (sambar) and then redirect them to the other mail server??????? Any methods.....

thx. n

    I don't beleive you'll be able to do that. You need multiple port 80's to send to multiple web based applications. This is going to require more than one external IP so that you'll have more than one port 80.

    Now, you could setup your webmail on another port and leave your setup just like it is. For example, if you set your webmail up to use port 8090, then users who would normally go to

    would use

    Other folks may know a way around one of the two scenarios above, but I do not.

    hi, there

    You could do as mentioned above

    Port forwarding on all kinda ports:
    80 to Webserver
    110 to email server
    23 telnet

    Or create your own port scenario
    and on the router just forward these addresses

    yeah, me and cooledit are on same page.
    Since your already doing port forwarding for 80 to the web box you can setup webmail to listen on 8090, or such, and do port forwarding for 8090 to point to your webmail server.

    Hope it works for you.
