Routing and natting Two different pools of public ip address

[sonacolombia]

Hi

I have a question about if something is possible with an ASA.

Actually the customer has the inside interface, a DMZ and the outside. For the outside the ISP deliver a set of IP address for all the servers and the inside network go to the internet and this will be configured as a default network in the ASA. A different ISP with 5 public ip addresses for 5 servers is also configured at this time.

Is there any way to integrate this in the ASA without contexts? (I need to set VPNs). If I put the main ISP as a default route for everything then I dont know how to make work the second ISP just for the five servers to go trought the internet and natting.

We know asa does not support policy based routing so we dont know if for the 5 servers we could go all traffic for the default interface and just public the natting of the public addresses for the second interface of the ISP so the traffic of this servers could leave for the default interface and return for the second interface.

Thanks

Hi Jose,

What code are you running for the ASA??? And you want to access 5 particular servers from your second ISP line????

This might be given a try as I have done it for versin 8.4. Do let me know.

Thanks,

Hi I've not done any code yet as im on the lab stage before going to the customer.

Yes, i want to access five particular servers from my second ISP line as they gave me a second subset of ip address trough a second line.

Is this possible?

Do you have a confguration you can share with me?

Thank you

Hi Jose,

Sorry for the late reply....

Yes we can possiblily do it, here's the config:

nat (outside2) 1 0.0.0.0 0.0.0.0

global (inside) 1 interface

static (inside,outside2)  

this should work for us, where outside2 is the backup ISP interface.

let me know how it goes, do let me know if you are using ASA 8.3 or later, beacuse these NATY commands would be different in that case.

Hope this helps,

Thanks,
