smtp is not responding on 2 external DSL Lines

sfischer over 18 years ago

Hi,

I have 2 external DSL Lines from different providers (arcor and m-net)
the external line from m-net has the default GW assigned. The 2. line has no default GW. Let's assume that two dns mx entries are pointing to line1 and line2
(eg. mail.mydomain.de with weigth 20 and mail2.mydomain.de with weigth 40)

If I try to telnet mail.mydomain.de 25 my astaro box is reponding.

If I try to telnet mail2.mydomain.de 25 my astaro is not responding.

What's wrong?
My goal is:
If dsl line 1 (mail.mydomain.de) goes down, that maildelivery will go through
line 2 (mail2.mydomain.de)

Any suggestions.

Thanks,
SF
