Subject Re: Virtual Router suddenly stopped working
Date Sat, 13 Jun 2020 13:42:20 GMT
Hello,
I found out the issue is with security groups. Some SGs are blocking DHCP
traffic. I already have ingress rules in place on the default SG. It works
for old VMs but it seems existing ingress rules do not apply on new VMs.

Please guide me.
