Hi,
We previously set up multiple Azure Site to Site VPNs using TMG and have added the VMs on those tenants to our domain.
We recently got a Sophos XG115 and struggling to set up a Azure Site to Site VPN. I managed to get the VPN to connect, however I am unable to connect to any of the VMs or ping them via DNS or IP. If I connect to the VPN via the Azure Portal I cannot resolve any users so I believe it's properly disconnected from the network.
On the Azure Virtual network it shows as connected and the same on the Sophos IPSec connection.
What I am noticing is in the Log Viewer the connection gets deleted every 5minutes without fail, then gets recreated 5-7 seconds later.
I have tried a bunch of different IPSec Profile settings but none of them seem to make a difference.
I have set up Firewall Rules for VPN - LAN and LAN - VPN with no luck.
I have also set up a firewall rule similar to how TMG had to be configured before which is Local and Azure network as source and local and Azure network as destination allowing all.
No luck with this rule as well, but look like some data went in and out of this rule atleast.
I'm no firewall expert, so I'm willing to admit if I was a idiot anywhere in the setup of this. But have been struggling to find any proper guides on this.
Will appreciate any help.
