Hey, guys,
I have a very strange problem on an SG 310 UTM 9.700-5 at a customer. There are several interfaces configured. Without any changes, the SMTP proxy does not listen on interface eth0 (192.168.0.99) since yesterday.
If I try to access port 25 via telnet, I get an immediate disconnect. I don't see an entry in the SMTP livelog either. Telnet to another interface on port 25 works at least until "554 SMTP synchronisation error".
Even a DNS query on eth0 doesn't work anymore, although it is released. DNS queries work on other interfaces.
I have already done a database rebuild and restarted the SG. The error remains.
I have already adapted the send connector to the mail servers, they point to another interface. Workarround works ;)
When restarting the SMTP proxy, according to Livelog, nothing unusual can be seen:

Did any of you already have this problem? Parallel to this I have also opened a ticket.
Thx 4 help!
