No sound/video MS Teams while using minemeld to pull Microsoft IP's

Hi,

 

When we start a teams meeting we have no sound or video, one to one call works! 

We use minemeld with palo alto to get list of allowed microsoft IP's.

But we see requests to the following microsoft IP's that are not in this list:

  • 51.144.76.36
  • 51.144.127.181
  • 213.119.108.243
  • 146.20.192.75
  • 146.20.192.80
  • 146.20.192.79
  • 62.109.232.228
  • 74.125.134.86
  • 51.145.129.18
  • 170.194.22.165
  • 62.109.232.153
  • 62.109.233.9
  • 62.109.232.147
  • 62.109.232.179
  • 74.125.134.85
  • 51.144.120.18
  • 51.145.140.46
  • 51.144.73.16
  • 51.145.133.231
  • 51.145.155.38
  • 51.145.152.56
  • 51.145.131.96
  • 51.145.159.119
  • 40.91.200.78
  • 155.56.38.222
  • 51.144.75.67
  • 62.109.233.161
  • 62.109.229.193
  • 51.145.153.45
  • 51.145.129.235
  • 131.180.0.234
  • 131.180.0.209
  • 10.21.15.32
  • 40.70.40.66
  • 62.109.232.253
  • 62.109.209.17
  • 74.125.134.87
  • 62.109.209.32
  • 62.109.233.215

 

We got confirmation from Microsoft that the above IP's must be whitelisted too.

Is this an issue from minemeld side or microsoft side that these IP's aren't present in the list that minemeld pulls from micrsoft?

 

Thanks in advance

Kind regards

Hi @JonasVanraes,

thank you for reporting this. These IPs are not present in the original feed from MSFT. I will report them, but before could you give me additional details?

- I see that some of the IPs are actually owned by Cisco for WebEx. How did you collect the IPs?

- Did you also use URLs? IPs are not enough usually

 

Thanks,

Luigi

Hi @lmori

 

Thanks for the quick answer!

 

We let the users setup a team session with video/sound and we looked in our palo alto logging to see which IP's were contacted at that specific moment.


Probably we took to much IP's out of the logging and therefor there are some cisco webex IP's in it too.
These can be ignored, sorry for that.

 

And yes we use the msft_office365_ipv4 list and the msft_office365_url list

 

Thanks in advance

Kind Regards
