Hi guys,   Just wanted to give you an update on my issue.   I might have gotten very close to the issue.   I have figured out that it is an old script running on an old server 2003. The script connects to an FTP ( Active ) Unsecured and uploads the files.   However, it does not work. Anyway, if I change it to passive mode. it works!   Going through the logs of the FTP transfer I find that it connects fine, and then times out. searching for this issue, it seems there is a bug in the specific software version of WinSCP they are running. that might cause this. I will upgrade the software and try it out again. best regards Daniel ... View more

Hi Philip,   How to do you mean? If I test it on a 4g circuit, and it works, wouldn't that mean it's isolated to that it's the Meraki thats the problem? 🙂 best regards Daniel ... View more

Hi Philips. Thanks a lot for confirming.   My boss is very sceptical, and thinks it might still be the Meraki, but I really think I have ruled out everything related to the Meraki in this case. I really appreciate all of your guys help 🙂 best regards Daniel ... View more

Hi Ryan, will try and check that.   Do you guys know if I need to allow anything specific in the firewall regards to Office 365? I do not have any outgoing firewall rules or anything like that. I can also send emails and receive emails fine.   I only have defined port forwarding rules, but not for office 355. Best regards Daniel ... View more

Hi Guys,   I have tried something else, maybe that could replicate my issue.   I logged on to their system and created a new file, filled it up with some data, and renamed it to test.EDN ( the file type navision sends with )   then I sent an email to another domain from their system, and I receive the email. Wouldn't that conclude that the file type is NOT blocked by Meraki? best regards Daniel ... View more

Hello Ryan_C Thanks for the input. I have now whitelisted the client. Just to make sure that is not an issue. Thanks a lot! will keep you guys updated on what I find out regarding this. I really appreciate you guys input 🙂 best regards Daniel ... View more

Hello Philip,   It was ment as an example. Sorry for the confusement. I have got updated information regarding the issue.   Basically what happens is that our costumer has an older version of Navision 2009. which generates a file ( EDN file ) which is then sent through office 365 by Navision to an email address outside the organization.   so basically we use Office 365 from the inside, sending an email with a file attached to an email address.   I have tried to disable IPS & AMP aswell. I read somewhere I might need to allow office 365 ? is that true? Everything with office 365 seems to work just fine. best regards Daniel ... View more

Hi Philip,   I have gone under both Security appliance and organization, filtered everything to only blocked. but I get nothing in the list. I would presume this means nothing has been blocked. if I filter "allowed" I get a lot of information 🙂   ... View more

Hi Philip,   Thanks a lot below. I would presume it means WAN to LAN only too by what you linked below.   Regarding the IPS. That would mean if the files has been blocked, I would be able to see it in the logs.   I could also try and disable to just for a test and see if the files get through. Personally I don't believe it's the Meraki blocking the files, but I will never say never. so I wanted to investigate it before I told them it's not the firewall.   I'm probably asking stupid. But the Security Report, is that the one I find under "Security appliance" -> Security center ? ... View more
