Current setup:
Local subnet A and B <<>> policy based vpn (cisco asa) <<>> vnet gateway <<>> dmz vnet <<>> 2 server 2016 vm's
Earlier today I was able to ping from local subnets a and b through to the two vm's and the two vm's were able to ping to the local subnets. At some point the service on my 2 server 2016 vm's went down (adfs web proxy) and I noticed I was unable to ping from the vm's to my local subnet A (ADFS server subnet) but I was able to ping local subnet B (monitoring subnet).
Things I have tried to fix this problem:
- Remove NSG rules so that we're running on base NSG
- Disable firewalls on both ends
- Reset vnet gateway using a powershell command
- Built two additional vm's and assigned them to new NSG (same behavior)
I have verified that the routes to local subnets A and B are similar and this was working earlier today and I have reverted everything I remember changing to try to get this to work. At this point I'm a little disappointed in Azure since what seemed somewhat simple has turned into a day and a half ordeal. Nothing I have done has granted me the ability to ping the ADFS subnet (A) since this issue started. I have checked a number of articles online and as far as I can tell everything should be working. Does anyone have a suggestion on next steps? Just to be clear - vm's in azure cannot ping any IP in the local ADFS subnet.
Thank you!
