Can't access Local File Server when not connected to FortiVPN

[parahvars]

Hi all,

I've got a weird issue with Fortinet's VPN where I'm not able to access my local file server unless I'm connected to the VPN, despite both my device and the file server being on the same network.

I vaguely remember having this issue about a year ago when I was using a different USB network interface, but this issue popped up again a few months ago when I moved to a new dock, and I've finally had enough, which is why I'm posting here.

I think maybe I edited my hostname file previously to give it the nics mac address, but I'm not sure.

Does anyone have any thoughts?

Hello

You may check the traffic log on your FortiGate, probably you are allowing access to your server from VPN and denying it from your local IP.

Hello,

Are you trying to reach via File Server FQDN or via IP.
Try to make a trace route where is the traffic going throw?

You should also check the VPN settings.

Hello @parahvars, 

You might need to run debugs to see which policy gets applied but as suggested by @AEK, you can check FortiGate logs as well.

diagnose debug flow filter add X.X.X.X
diag debug flow show function-name enable
diag debug flow show iprope en
diagnose debug console timestamp enable
diagnose debug flow trace start 1000
diagnose debug enable

regards,
