Record a SMTP flow through a WAN interface (alias) with SMTP proxy enabled

mehdi
Morning,

In WAN infrastructure where there is 2 WAN interface A/SDSL.

i meet some difficulties to bypass my SMTP flow by a specific WAN interface (alias) where is set my MX recorder, knowing that my SMTP proxy enabled.

the problem that the outgoing SMTP flow always through by the defaut WAN interface.

Previous attempts :
i had set a multipath rule binding by interface on the right WAN interface (cause there're two WAN interfaces)
i had also already set a SNAT rule by assigning the right WAN IP alias (MX).

How can i proceed? any ideas are appreciated..

Thanks in advance.

K. Regards,
mehdi

    If you have Uplink Balancing configured and both WAN connections have a default gateway, then a multipath rule should work.

    To use a SNAT instead of a Multipath rule, you also will need a Policy Route.

    Please show your Multipath rule.

    Cheers - Bob
