Change IP Address Management on Azure in FrontEnd Network
Hi
I have a Check Point Firewall on Microsoft Azure. I can manage the firewall throught Public IP Address. However, I note, after firewall deployment, that the Private IP Address associated to the IP public address had a wrong subnet mask.
I Changed the subnet mask on Gaia and firewall objects and the rules were installed successfully. However, when the subnet mask is changed on Azure, I lose connection to the firewall management from Internet.
To ilustrate best this scenario, I explain it with an example:
The eth0 interface have a Private IP Address 192.168.1.1 mask 255.255.255.248
The eth0:1 subinterface have a Public IP Address 200.xxx.xxx.xxx
When I change eth0 interface to Private IP Address 192.168.1.1 mask 255.255.255.240 on the firewall and install rules, the firewall acts successfully.
When I update the subnet mask on Azure I lose connection to manage the firewall and I need to return to the before subnet mask.
In this moment the subnet mask on the firewall is 255.255.255.240 and the subnet mask on azure is 255.255.255.248, but I need configure the same subnet mask on both.
Any ideas about how to solve this?
Thaks for your help.
