We have two S2S VPN's that go to a remote office. One that goes from Azure to an ASA and one that is from a Sophos Firewall to the same ASA..
From computers in Azure and the site that has the Sophos Firewall, I can RDP to computers at the site with the ASA
From the remote office with the ASA, I am unable to reach any computers in Azure or the Site with the Sophos Firewall.
Both tunnels show up and passing traffic.
