Re: Virtual Router suddenly stopped working

[Fariborz Navidan]

I checked iptables rules and noticed when new VM is created, no iptables
chain is created for it on the host. SGs don't work.

Please assist me.

Re: Virtual Router suddenly stopped working

[Fariborz Navidan]

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.

Yes, it can ping the VR if I configure the allocated IP on the VM manually.

Re: Virtual Router suddenly stopped working

[Andrija Panic]

If you configure the IP (from that network range) manually on the VM - can
you ping VR IP (inside that network) - i.e. is there LAN connectivity
between a VM and it's VR?

Re: Virtual Router suddenly stopped working

Have you checked the management logs, Sometime router goes in read-only file 
system, So in log it says - unable to apply dhcp entry on router and file 
system in read-only mode ( something like this ).  If this is the case then you 
won’t be able to provision any  new VMs.
