stack of 8 IP's, new MCI router

[encinitas]

hello,
moving to a new site Friday. I'm getting a router from MCI for my new T1. Not sure how they will configure it, but it gets sent to me tomorrow.
I have a PIX to PIX VPN, and Exchange, and some remote clients using Cisco Dialer.
So do I use one of the 8 IP's as the "outside" IP, and another one as the route outside?
I'll have an MCI tech helping me, I think. I just need the router to pass the right info to the PIX, like the authentication for my Cisco dialers, Exchange, etc.

thanks in advance.

one of the public ip will be assigned to the router and the rest of the ips will be forwarded to PIX. Make sure that there is no nat or firewall on the router.

The router should just do that, routing. Meaning all of your traffic will be routed to your Pix. Are they requiring you to change you IP subnet to the new /29 net or is that in addition to your existing network?

networkghost-
we're changing from SBC to MCI. My new range is x.x.144.224-231 , and MCI tech said to use .225 for the router.

so, on my PIX, which new IP should I use?

here's current:
ip address outside x.x.128.10 255.255.255.248
route outside 0.0.0.0 0.0.0.0 x.x.128.9 1

change to:
ip address outside x.x.144.226 255.255.255.248
route outside 0.0.0.0 0.0.0.0 x.x.144.225 1

does that look right?
and the .226 is now my Exchange/VPN public IP?


******
ok- just got an email from MCI tech:
"Try using Router x.x.144.226 and the 225 as DW."
what is DW?!

thanks in advance

ok- i made the change, put in the new IP's. here's my status:
i can send mail out, can't receive it. i can ping mci's dns from the PIX, i can surf the web, can attach to my mail server using

https://newipaddress

, can't ssh into the PIX, can't use the Cisco VPN dialer with the new IP.
I send my mail through a spam filter service first, and i changed my IP on their web GUI a couple hours ago. a tracert from them is successful, but a latency test is not.
any thoughts? mail is most important. is it the DNS propogation? i changed mail.mydomain.com IP a couple hours ago too and a ping still point to it.

thanks in advance

ok- i think i found what the culprit was- the access list 103 still had my old ip for smtp.
i can vpn in now and ssh.
the other config was on a newer PIX, new OS version. I'll swap it out later, after the rest of the move.

thanks-
