Block cameras from everything but email

(1/6) > >>

Hey guys, trying to get my Hikvision cameras to send email notifications.  I was trying to figure out why it wasn't working then I remembered i blocked all access to the internet for them so they don't get hijacked or hacked.  Is there any way to just let them send out emails but block everything else?   I have a block all rule in the firewall settings.

Everything is done either by port or by src/dst address.  Use your block log to figure out how & where it's trying to talk to send emails, and then craft rules to specifically allow that traffic.

thanks KOM, it just needs to get to googles email servers.

Make an alias gmail_smtp_submit for FQDN

Put a pass rule above your block rule for TCP destination gmail_smtp_submit port 587

In that case, ask Google :  ;)
