Chrysler Network infrastructure is implementing some changes that will change the resolution of the ebmx.extra.chrysler.com DNS. The date for this has been set as: 7/19/2009 @ 00:00.

If you have your server/PC behind a firewall, and the following IPs now need to be allowed:
129.9.70.68
129.9.102.68
129.9.102.69
129.9.70.69

Note that, due to the redundant, load balanced configuration of EBMX, Chrysler cannot guarantee which of the four IPs will be the resolution to ebmx.extra.chrysler.com at any one time, therefore, they suggest all four be configured as allowed.

Below is the note from Chrysler that you may have already received:
**************************************

ATTN: All HTTPS Mailbox and AS2 User’s of Chrysler’s EBMX (Electronic Business Message eXchange)

Chrysler Network Operations will be implementing an infrastructure change on:
7/19/2009 @ 00:00 EDT

This will CHANGE the IP resolution of:

https://ebmx.extra.chrysler.com [DNS for HTTPS Mailboxing]
and
http://ebmx-as2.extra.chrysler.com [DNS for AS2]

Most suppliers/trading partners SHOULD NOT be affected by the above change.

Very few suppliers/trading partners have specific firewall rules which will prevent communication with EBMX after the change.

If you are one of these suppliers/trading partners, please contact EBMX support via email:
ebusdesk@chrysler.com

or, via Chrysler’s Service Desk:
call: 800.332.9978
open a ticket – ensure it is routed to ticket group: EBMX

Please ensure you provide your name, company, supplier code, phone and email.

EBMX will supply alternatives to the firewall configuration to ease conversion. The new IP resolutions will also be provided if required.
