Sharing database via Dynamic DNS service?

Recommended Posts

Hi everyone,

I posted an issue about sharing a FMP file on my internal network a few weeks ago, and have now moved to the next level - I now need to share the same FMP file remotely.

In the past I have used a Dynamic DNS service (No-IP.com) with Remote Desktop to access my home iMac, but is it possible to use this service to access my database when I'm traveling via my MacBook Pro?

Sure.  But you'll get the SSL warnings since your dynamic DNS name cannot easily be covered by an SSL certificate.

Note that you will need to set up your firewall and router to allow for and forward the FM traffic to your internal FMS machine.

Thanks Wim (are you the only Expert reading these forums? LOL)

Can you explain how this type of "hostname" sharing needs to be setup between my "home" .fmp12 file & the "remote" MacBook Pro please?

  1. I've setup a free account with No-ip.com and have a hostname
  2. I've setup my router to allow for port forwarding using the No-ip service (Advanced/DDNS enabled)

I'm presuming my next step is to contact my ISP to check which ports I can forward - is there a specific port I need to use for FMP file sharing?

Then presumably it's just a case of adding the hostname to the "Hosts" section in the File/Hosts options.

On #2: I don't know what that looks like exactly on your router, typically port forwarding doesn't have anything to do with with the DDNS.  The router's DDNS settings usually are there so that the DDNS service is made aware of your router's WAN IP address, but does nothing for port forwarding.

So I think you don't have the port forwarding set up yet.

You don't need to check with your ISP, FM has a set of ports it uses but the main one you need to open and forward is 5003.  If you use interactive containers in your solution you'll also need ports 80 and 443.  If you also want to use the FMS admin console remotely then add port 16000.

If this is set up correctly then the last step is to add your DDNS host name as a favorite host in FM.  That'll make it work from home.

In the office you can just pick your server from the local list.  If you use the DDNS name from inside your network, chances are that performance will suck if your traffic is routed outside of your network to come back in on that DDNS name.

Hi Again,

Looks like this is not going to be possible - just had some interaction with my ISP support team who advise port forwarding to 5003 is not possible because:

"The reason it isn't working is you are on a CG-NAT IP address."

      I am using Filemaker Server 18 on Windows Server 2012 R2
      Been using it for years with no issues
      Currently when I log in to the console it is very sluggish.
      When I get to the Dashboard it shows No databases, then it auto refreshes and the database list appears.
      Within 15 seconds of scrolling the database list to open files the screen refreshes. This situations is happening over and over in a loop.
      Any Thoughts on what is causing this issue?

      I get an error 3 when using a script to Export Records via WebDirect. Using FileMaker Server 18 and have tried both Safari and Chrome both with same results. I have tried using the temporary path, desktop path, and documents path. I have tried using with the automatically open and not. I have tried writing a tab delimited and comma delimited file. Does anyone have ideas I haven't yet tried?

      Hi All
      I am hoping some one can help!
      I have a table called TPM, in that table is a field "Next Due Date" Which is auto generated by creating a new record. You input the date you did the service and then it adds 3 months to that date and that appears in the Next Due Date Field.. All working...
      What I am trying to do is when the database loads it runs a script to see if there are any outstanding TPM Services to do...
      Here is the script
      Show Customer Dialog
      Message: If ( TPM::TPM Next Due Date < Get (CurrentDate ) ; "You have outstanding TPM services" ; "You have no outstanding services")
      I thought it would be that simple. So I created a TPM Due date Less that Current date and ran the script...."You have outstanding TPM Services"...GREAT! Then I deleted that record and ran the script again...""You have outstanding TPM Services" Oh!!! That isnt true!

      My issue is that my customer layout has a script trigger on LayOutEnter that sorts my customers portal list by "Active" customers,
      but when I do a go to related record from another table say from quotes or any other the customer layout does not load that customer
      or show my related customer because the OnLayoutEnter script trigger changes it, I would like it to go to the related customer and also sort it by "Active"
      on the list.
      Hope someone can help me with this.
