Hi,
The basics are we have a head office and a remote office both with their own XG firewall's connected over an IPsec Site-to-site VPN, there is no issue with accessing one network from the other and AD authentication is setup and working in the head office. I'd like to enable AD authentication on the remote office XG as there is a file server located their but it doesn't have a local AD server, just the one in the head office. I've tried setting it up so it points to the AD server in the head office but the connectivity test fails. I've setup a firewall rule that allows all traffic to pass between the networks, is there something I'm missing a rule/setting or will it just not work across a VPN?
Thanks
