DNS Port Redirection

I have 2 servers one of them SBS 2003 and the other Server 2003.  I have one static IP address that goes out the outside, which points to the SBS 2003 Server.  I have set up mail.domain.com to point to that server and I have mail.domain.com:9999 to point to the server 2003 server.  How can I convert that mail.domain.com:9999 to something easier to read like apps.domain.com? What do I need to do to redirect it?
Should I be doing it from a different route? Please direct me.  Thanks

This wouldn't be a DNS issue, but a routing issue.

I believe there is no way to specify a port in DNS.  DNS is just meant for address translation to ip.
SMTP is standard on port 25 so you will need either 2 IP addresses or to relay the mail from server 1 to server 2.

Get another IP from your ISP and just make 2 routes.  Then you wont need port translation.

well you have to make a DNS entry.  Not sure if you host your DNS internal or pay someone else too.
After you have the DNS entry you have to configure whatever routing device your servers are using.

Are you using NAT?  Or assigning internet IPs to the servers directly?
What kinda of router are you using?

Alright.  So the 2003 machine must be behind the ISA SBS machine?

Is the 2003 machine using a 10.10.x.x or 192.168.x.x ip address for its network card??  Or is it using a address the ISP gave you?

We will have to make the routing adjustment in ISA, and probably a firewall modification.

Yes the WIN 2K3 is behind the SBS.  The 2003 machine is using the 10.10.x.x.x ip.  The sbs is using the ip address from isp.

alright so you add the new IP to ISA, then build a route in ISA that translates the IP to the 10.10.x.x of your 2003 machine.  After that make sure the firewall allows traffic on that IP to the 2003 machine.

Then if your dns is active you should be able to use it from the internet.
