We just implemented a BlackBerry Enterprise Server for a small base of GroupWise users and I'm having a small issue with the wireless bypass capability and the BlackBerry Router.

How can I control what IP address/hostname is presented to clients for the BlackBerry router? Right now, it is picking up the server's internal DNS name, but this isn't resolvable from everywhere it needs to be... If I manually add the external DNS name of the BES to the BlackBerry Router configuration in the handheld manager then bypass works, however, I'd like this to be the address that is configured as part of activation of the handheld instead of the server's internal DNS name.

Any way I can change the DNS name that the router knows itself by and do I have to resend the service books to the handhelds after making this change?

Thanks.

As far as I know this option is not configurable. You can only set the router's host in the BlackBerry Server Configuration and it has to point to your router whether it be localhost or a remote machine and this I believe is the address that is sent to the BlackBerry's in the service books. You may want to try and have the router running so that the same hostname is accessible internally and externally, also keeping port 4101 open as this is what serial bypass uses.
