  • Migrating WAN connection

    Hi all,


    I have a small question. I am expecting to have issues with a planned WAN migration. I run a Win2k3 SBS at home with OWA, VPN, sharepoint and what not... The problem is that the current ISP does not block any ports, and the new ISP will block everuthing below 1024. But the new ISP has 4 times more downstream and 5 times more upstream... So I really would like to switch.

    The questions:

    Will I be able to run OWA on a different port? If so, can I use http://domainname : port/exchange instead of https://domainname/exchange?

    Will I be able to use Outlook Anywhere (Outlook/Exchange over http)? I believe it only works with 443 wich by then will be blocked by tyhe ISP. Is there a workaround on this, except using VPN?

    Will VPN work if everything below 1024 is blocked?


    Any input will be very appreciated...



    Grtz

    Are you sure about this? Ports 80, 110, 21 & 53 are 4 of the more commonly used ports below 1024 and your ISP is blocking them?
    Web browsing,
    POP email
    FTP
    DNS

    I suggest you get clarification from your ISP exactly what ports are blocked (or not blocked) and ask if they will open specific ports for your account.

      After you verify what you say is true (though I am with Biggles77 in my opinions) you could do OWA say on https://<FQDN>/exchange:2000 (or is it https://<FQDN>:2000/exchange?)and let your router translate port 2000 back to 443.

      Never tried it myself, but it sounds possible - you just have to remember which port translates to which all the time and tell your users......

        Hi guys,

        Thnx for the replies...

        My neighbour has the same ISP I'm mograting to, and if we setup NAT'ing on his router I cannot connect. The ports seem to be open inside the ISP's network, so if I try to connect from let's say a hotspot on the very same network, everything is working...

        The general idea here is that you aren't allowed to run a webserver on a normal subscription. If you want to, you need a business subscription with a fixed IP and stuff. That's much more expensive...


        I'll take this up with their customer service, but I tried once, and when I asked my question the guy 'had to check that' and I was on hold for 7 minutes - eventually hung up.

          I know this to be somewhat true with Earthlink. They will not allow incoming SMTP connections with a dynamic IP address, only with a static "business" ip address.

            Lukas, ask them to escalate your call and/or ask to speak to a supervisor. Also, 7 minutes is nothing. They just want you to go away. (My record is 47 minutes then they disconnect me so I called back. A PC with a hands free phone next to it ........ another 40+ minutes and I get my answer) but I digress.

            Another option is to talk to their Sales people but make sure you get a confirmation email if they have promised to open ports.

              And for a Small BUSINESS Server you should really be using a BUSINESS class line - even if it does cost a bit more.

                The connection has been migrated and what I was affraid of happened... VPN dial in works just fine, but http and https is blocked. Just page cannot be diplayed...

                So I'll have to move the IIS sites to a port higher than 1024.

                As for paying for a bus. connection: keep in mind that my sbs setup is an hobby, not a corporate environment or a small bussiness... it's just me, my girlfriend and my neighbour that use the server. I need OWA for my girl, so she has all her mail in one place (at her home and at mine)

                So I don't feel like paying triple the price I pay now for the same bandwidth and a static IP.


                Thnx anyways for the replies guys, I'll try tio change the settings tomorrow and report back. I don't hope for Outlook over HTTP anymore... That just ain't happening.


                Thnx again,


                Lukas

                  It may be cheaper to marry your girlfriend and have her move in to your place. That way she can access her email internally and you'll get a hot cooked meal every night.

                    Quite expensive for a home setup. I would choose for a Linux enviroment for a home setup.
                    However, I think if you can buy a SBS server you also can buy a business Internet feed.
                    Or just search for an other ISP.

                      If you check Lukas's post history, he was apparently given SBS premium by a generous employer. I also wondered about this.

                        Re: Migrating WAN connection

                        Thnak you for all the replies guys..

                        Yeah, it's an licenced copy, original media, hologram on the cd's and what not... got it indeed from my employer, and the OS is legit, activated and licensed... The key is unique and only used on that machine. The machine is fully patched and WGA complient. Just to get misunderstandings about hacked/illegel software out of the way...

                        As for my girl moving in: nah thnx. And I have a microwave as well

                        As for the price of the setup: Win2003 is a gift, Vista workstation is OEM version, OpenSuSe 10.2 is free, and my laptop runs the OEM XP Pro. SBS runs on old hardware; Intel processor, I think a 2800Mhz, with 2gig of RAM. And the ISP charges me 61 euro/month for 20Mbit down, 1 Mbit up and 35Gig of volume. So no - actually it's a pretty cheap setup I got at home (except for the electricity bill) - but that's kind of off-topic.

                        Now, back to issue at hand. I managed to move to the setup to ports 8800 and 4443. All I had to do is add the ports in IIS, NAT them on the router... and voila, it worked.

                        However - and I dont know if this is the right place for this problem - My Smartphone wont sync with my exchange anymore. Im running windows mobile 6 and active sync tries to resolve the port number as well and still tries to connect on 443, even if :4443 is specified in server setting on the device. And it tries to resolve fqdn : port instead of the fqdn, while trying to connect on the : port.

                        Seems like ActiveSync doesn't like portnumbers. Any tips?

                          I'm pretty sure Activesync will not talk to alternative ports
