Multiple IP addresses through T1 and Cisco 2600

[kevin2liu]

Hi,

My company has a T1 connection to the Internet. we have 10 IP addresses from our ISP. we have a Cisco 2600. Now we are only using one IP for web casting service. I need to setup a new machine and install SQL Server in it so that it can be used as a job ticket management system, it needs to be accessed from within and outside of our company. So I am thinking that I should use another IP address (which we already have from our ISP) for the new machine. (Because I don't want it to bother the web casting service.) But I only have one router. Do I need to buy another router to accomplish this? how to set up?

I appreciate any help!

i just replied to another poster with a similiar situation.

actually first look at static nat (i am not 100% sure that this can be done with it but it may be possible)
you may be able use 1 ip and map each different host to the destination port that Inet users will use (ie. SQL tcp 1433 udp 1434) ala port forwarding
like i said before i am not 100% sure that this can be done with nat static (as i have never even attempted to used it to do port forwarding) but it is worth looking at if you don't wanna spend the money.



here are your other choices

1
A pix firewall can accomplish this using port forwarding without problem
(i have done this)

2
A free floppy based LRP linux firewall such as Dachstein or Eigerstein (Seawall) can do this without problem
(i have done this)

send all traffic that hits the firewall destined to tcp/udp 1433/1434 to the SQL server at 10.1.1.10
