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)?

  • Yes - I know.
    That is why I will only use the alternative port from client to firewall and then redirect in the firewall to standard 443.
    So my question is on the client side.
    Regards.

    Is your GMS running on its own instance of SLES, separate from WebAccess,
    but you have only the one public IPv4 address to work with?

    Yes, that is the exact situation.

    As others have pointed out, depending on the device you may or may not
    be able to specify an alternate point. I know your question is
    regarding iOS, but even then, there's always the possibility that an
    iOS update could break this even if today iOS allows specifying an
    alternate port.

    If anything I would keep GMS on standard 443 because of device
    limitations and then use an alternate port for WebAccess. You can
    always specify the port in a URL in a browser. That would be much
    safer.

    Instead of doing PAT at the firewall, just do straight NAT and set your
    GMS or Webaccess to the port you are using so that it is the same port for
    client as well as what GMS or Webaccess is using. Also make sure it isn't
    a common port or too high up, 1443 is a commonly picked one for those of
    you in your situation.

    If it is still a problem, it would be worth capturing the packets of the
    attempts coming in, either at the firewall level and/or on your GMS or
    Webaccess server.
