IPFire S2S IPSEC Azure


For a customer of ours we are trying to setup an S2S IPSec VPN connection to Azure. We ourselves don’t have any experience with IPFire. We manage to setup the connection. But the issue we are having is that traffic is only going one way. We can send packages from the internal network to Azure but not back. We have double check all of the settings and all seems to be good, especially on the Azure side. To confirm the Azure side was good we setup the connection to another firewall and that worked. So the issue seems to be on the IPFire side. Anyone have any experience with this?

Here are the settings of the IPFire:

We are currently running version 163, will update to the latest version tonight.
Any help would be apricated
