Unable to access Sophos firewall in Azure when a new interface is added.

Hi,

We have a vnet in azure with 2 address spaces 10.50.x.x and 10.90.x.x. We have deployed a sophos firewall there and added 2 subnets in 10.50.x.x as lan and wan networks. We also need to have 10.90.x.x network connected to the firewall. When we try to do that by adding a new network interface, we lose access to the firewall. If we remove that interface, the connection comes back up. Can you help us with this issue?

Thanks, Arosh.

You should not add interfaces to the firewall, instead you connect the networks to Azure using the Azure techniques. https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-peering-o…

Hi,

probably means the interface order has changed so your addressing will move to the new port.
