I have two IP ranges coming from one provider over 1 T1, both are /29's. I've recently purchased an ASA 5510 to protect the office, but can't seem to make use of the second range of IP's. I'm connecting to a Cisco 2500 router and it all works fine with no firewall.
I have the second IP of the first range as eth0/0 and the second IP of the second range as eth0/0.1.
I'm sure it has something to do with routing, but I don't know how to specify the "next hop" as I do with the router in the policy route.
I'm at my wits end and fear that this firewall doesn't have the capabilities I was told it did (by the salesman of course).
Thanks,
Steve

Hi ... if I understood your scenario .. you have 2 public ranges right ..? and I believe you want to use them on the ASA right ..?
Is the ASA going to replace the 2500 router ..?
Can you elaborate a quick network diagram to understand what are you trying to achieve.

Yes, two ranges and want to use them both on the ASA. I intended to leave the 2500 in place as I don't have a T1 card for the ASA.
I've thrown together a quick network diagram of how it "should" work. Just to reiterate the original post though:
from the outside, I can ping router just fine, but I can only ping the xxx.xxx.239.58 interface, this is because I have a default route on the ASA of xxx.xxx.239.57. There's no route for the xxx.xxx.237.0/29 network on the firewall. (although oddly, the router can't seem to ping the xxx.xxx.237.2 interface even though there on the same network)
The ASA is configured such that Eth0/0 is xxx.xxx.239.58/29 and Eth0/0.1 is xxx.xxx.237.2/29.
Thanks for any help!

Am I to believe that this device can not handle more then 1 ip range? If anyone could answer before my time is up to return this unit I'd greatly appreciate it.
thanks,

you diagram does not look right .. are you able to provide the config of the 2500 router and the ASA ..
You have been given 2 public ranges so.
1.- you can configure one public range for connecting the ASA to the router ( I believe you have used x.x.239.56/29 segment ).
2.- The other range can be used as a DMZ on the ASA. You can allocate an IP address to one of its interfaces on this range ( I believe you have used x.x.237.2/29 ).
3.- You can't have x.x.237.1 on the router and x.x.237.2 on the ASA. You need to remove this from the router.
4.- You can use a third interface on the ASA for connecting your internal users.
5.- The ASA will be protecting your internal users in that way.
6.- You also need to make sure your ASA has default gateway pointing to the router.
7.- you need to make sure the route has a static route for x.x.237.0/29 pointing to the ASA.
I hope it helps ... please rate it if it does !!!
