Send Emails with Gmail

[Jon_Palo92]

Hello friends, I'm trying to setup my home firewall with the Gmail (or any other free SMTP server) but the test failed with both Gmail SMTP and SMTP relay. The firewall is able to ping and resolve the dns name of the SMTP server.

Connection to: smtp.gmail.com:465 failed: Failure when receiving data from the peer

Connection to: smtp.gmail.com:465 failed: Failure when receiving data from the peer

Connection to: smtp-relay.gmail.com:587 failed: Failed sending data to the peer

Connection to: smtp-relay.gmail.com:465 failed: Failed sending data to the peer

Do you know if there are some steps need to follow in order to resolve this issue ?

Hi @Jon_Palo92 

I have tested this personally using smtp.gmail.com in my LAB and it works well. Configuration is more on your GMAIL account side where you need to generate app password. This app password generated for your GMAIL account will be used to configure on your firewall under SMTP server profile configuration. For gmail side configuration, there are so many videos available on youtube which you can refer. I had personally referred same and I was able to get this work.

Apart from this, just make sure Palo Alto is able to communicate on required ports.

Hope it helps!

@Jon_Palo92,

Just to extend on the tail end of @SutareMayur's correct answer, I'd verify that the traffic is actually being identified properly and being allowed in your traffic logs. If you don't already have a logged catch-all entry at the bottom of your rulebase, enable logging on your interzone-default rule at least temporarily so you can see potentially denied traffic.

Yup,  that worked. I needed to do the Gmail stuff. Thank you very much my friend!.
