Astaro can't receive emails on 2 ext. interfaces

Hi,
I have 2 external interfaces.
SMTP poxy is only responding on that interface,
which has the gateway configured.

If I do a
telnet 25 and
telnet 25
only the interface with the gateway responds.
Why?

I have 2 ext lines, and both ip's have port 25 open. Is there another firewall in front of one line?

Hi,

because calls to interface 2 will return via interface 1 (default GW).

Use an Alias interface instead (second IP address on first external card).

Hi,
I added a second IP Adr on the first interface
Result is the same, Interfcae without GW is not
responding to SMTP.
Any other ideas?

Hi,

strange. Can you go to console as root, and enter
iptables -L | grep smtp
and
netstat -a | grep *:smtp

I don't mean to hijack the thread, but I'm experiencing the exact same problem.

Here is the output of the commands as per the instructions:

Code:

cerberus:/home/login # iptables -L | grep smtp
CONFIRMED  tcp  --  anywhere             anywhere            tcp spts:tcpmux:65535 dpt:smtp CONFIRMED 
CONFIRMED  tcp  --  anywhere             anywhere            tcp spts:tcpmux:65535 dpt:smtp OWNER CMD match exim CONFIRMED 
cerberus:/home/login # netstat -a | grep *:smtp
tcp        0      0 *:smtp                  *:*                     LISTEN      
cerberus:/home/login #
