Good morning,
since I've been working from home using VPN access to connect to the office I noticed, I haven't been able to access my companies external email server. is there a Splunk Query I can run to give me a little more insight into why I am unable to access that external email server?

Any assistance in that regard would be greatly appreciated.

Thanks

Cosmo

Hello @cosmo0630,

depending on how VPN is configured, only internal or all/any traffic can be send to HQ. If any traffic is being sent to HQ then most probably the internal firewall doesn't allow an access from HQ to the external mail server.

To find something in logs try

index=_* (ERROR OR WARN) (mail OR SMTP)
