Can I define a mail server

Jump to solution

Hello,

I'm trying to use a new wireless connection, ISP #2

ISP #1 is a half meg ADSL service...too far from the CO for anything faster, and I have no cable service on the street we are on.

I'm having problems with mail server settings. Neither ISP #1 or #2 allow the use of an alternate mail server.

Neither of these solutions is going to be bullet proof, so I will need to use the failover.

When the SG560 loses one connection, and switches to the next, our mail stops sending. The clients, Eudora, are set with smtp.isp1.ca or smtp.isp2.ca

I'm in way over my head right now. Other than move the business to a location that is better served, I'm stuck.

Is there some way to have the SG560 send the mail to whichever server is associated with the connection that is up?

Or...since the DSL is mostly up, but slow, can I leave both connections as primary, and use the dsl for mail only?

Thanks

John

it is possible that the connection tracking is keeping the traffic on the wrong link due to prior traffic on that link.

I know it is a pain, but can you enable both connections and see if the issue occurs after a reboot ?

If issues persist, I think you will need to lodge a support ticket so I can see the full diagnostics of the unit.

see

network sutup -> routes -> policy routes

you can route traffic out a specific link based on either source & destination address and/or port number

Let me preface this by saying that I hope all you people are safe, and dry out some day soon!! It looks to be absolutely horrible in NE Australia.

I shouldn't get excited about this stuff, but this seems to be exactly what I need!

If I do this, am I on the right track?

Enable = Check

Type = Output

Incoming Interface = None

Source Address = LAN (Switch A 192.168.99.1)

Destination Address = Any

Services = SMTP

Gateway = ADSL Port A4- which matches the client setup.

Thanks, and stay safe.

The rule should be

Type = Forward

Hopefully we will dry out before the next rain comes  ;P

I think I'm probably all around the right setup for this. Just can't get it to work once I enable the 2nd connection.

This is where I've left off.

Enable = Check

Type = Forward

Incoming Interface = LAN (Switch A)

Source Address = Any

Destination Address = Any

Services = SMTP

Gateway = ADSL (Port A4)- which matches the client setup.

Hi Ross,

The reboot fixed it. The more I learn about this little box, the more I like it. It's a shame it's going EOL. Hopefully someone will pick it up.

Hope your world dries out.
