Strangeness with EDL - for Office 365

Hi

 

I have minemeld mining O365 address for my PA's.  Moved to the new API as well.

 

I have a hybrid Exchange setup.

I have moved some mailboxes up to the cloud

What I have found recently is mail stops flowing 

 

I have a rule that basically say

 

MS Public IPv4 to my beachhead port 25 smtp

 

O365 attempts to talk to me and gets blocked.

I check the src address and its in the EDL range.

If I clone the rule and place it below it and then commit and push (from panorama) 

once the push has finished it starts to work . same src ip and it matches the original policy.

 

almost like there is a TTL on the edl ip addresses 

 

Now I have the EDL set to refresh at 6am.  guessing I can change that to every hour ?

 

Any one else had issues

@Alex_Samad,

What's the target firewall and what PAN-OS version is it running?

pa-5220

8.0.12

 

 

I have done a 

 

resquest system to look at the EDL - and the right ip address range is there

I have done a test and it matches against the right policy.

 

and the way I have been fixingin it recently is to do a 

request system refresh on the edl
