EGX 300 E-mail log export error.

[Anonymous user]

Hi,

   I am trying to configure the EGX 300 to do an export through smtp but I got an smtp connection error message. I am using my personal gmail account to send out the log.

   Below is my setup.

Regards,

Razali.

it looks like a firewall is blocking the outgoing traffic on port 465 (that's explains why the telnet / port 465 does not respond)

==> try to see with your IT manager

To save your time:

1) EGX300 firmware v4.380 does NOT support neither SSL nor TLS for connection to SMTP email server.

Port can be freely changed from the default 25, but that doesn't mean anything . Putting there a port that people know as "standard" for SSL, involves no commitment for an encrypted link using SSL or TLS.

Use an intranet email relay server which accepts un-encrypted connections from your EGX300 and from there to smtp.gmail.com use a TLS (port 587) encrypted link.

2) SMTP authentication method: Plain / Login / CRAM-MD5 / Digest-MD5

3) And, yes, HTTPS data pushing is supported. Although everyone gets rid of SSL in favor of TLS.

4) smtp.gmail.com <> gmail.com

5) for your fun, try a "telnet smtp.gmail.com 587" it will work.

Hi Adrian,

   Thank you for the reply.

I have tried another method to go around this, I installed a mail server on my laptop and use that to send out the log. I might be wrong but I think the issue with using gmail as the mail server is that its IP is always changing. I tried to ping gmail.com and i got x.x.x.213 and 1 hour later i got x.x.x.210. But with the mail server installed on my laptop I am able to send out the log successfully.

Hi, thanks for follow up.

The gmail's SMTP IP is changing periodically and frequently. That's why, @ #1 in my initial answer, I recommended to "Use an intranet email relay server which accepts un-encrypted connections from your EGX300 and from there to smtp.gmail.com use a TLS (port 587) encrypted link."

- Intranet email server must have a fixed IP address and this is required by EGX300

- Intranet email server must know how to resolve host names into IP

- Intranet email server must accept unencrypted connections as this is required by EGX300

An Intranet email server can be hosted on a computer that you can control (as you did already on your laptop) or on one of your company's servers.

The different IP addresses are probably due to a proxy spreading the load across multiple physical servers for load balancing and redundancy reasons.  My guess is that all the IP addresses you are seeing probably will work so just pick one and see if it works over time.  If this do not work then you are no worse than you are right now so you only lose a little time trying it out. 🙂
