I have a small problem I need an answer to.
Basically I have an Astargo ASG220 ( V7.505)
with 2 adsl lines attached for uplink balancing.
On the other side of the unit (intenal) I have an exchange server on ip range 192.168.x.x
as well as my internal network.
My question is how do I ensure that the smtp traffic always leaves the astaro via the correct adsl line.
This setup works most of the time unless I do a reboot and then the SMTP traffic starts to go out which ever line re enables first. I want to force the SMTP traffic only to use 1 now matter what.
The mail still gets through on either line but obviously when the receiving server does a reverse DNS it does not match and the email is rejected.
Thanks in advance
