Using a alternative port for a GMS client

Hi,
I know this question is not directly GMS, but I have been searching Google and Apple without finding the answer.
I want to have GroupWise web access on default port 443 - and I would like to use GMS to get mail and calendar on iOS clients.

So I will make a NAT rule in the firewall translating an alternative port to my GMS server on port 443.
Can this alternative port be configured in an iOS mail account (Exchange type)?

    I believe ActiveSync uses port 443 for SSL/HTTPS connections and 80 for
    non-secure HTTP connections and that these cannot be changed to
    different ports.

    HTH.

    Depends on the individual device. Many can specify alternative ports,
    but also many can't. Last I checked, IOS could, Android generally only
    4.3 or higher and some older specific devices (HTC for instance always
    could do this), Windows Mobile up to WM7 can't chnage it. No idea if
    they can now.

  • Any idea of the syntax on iOS?
    A-record.domain.dk: port seems doomed as invalid,

    No, sorry, I'm not an Apple User, I was told by one (actually multiple)
    that it works. There are also hints to be found in google that it does.
