Re: Lost connections - EFA stop working

Update


The SMTP connections are not showed in /var/log/maillog

All my test from internet to EFA don't appear in the list.

I got also problems with interface.

I use 2 virtual interface so that I can route 2 wan with public IP to the 2 internal interface.

My configuration is

WAN1 NAT to internal interface 1 10.10.10.16
WAN2 NAT to internal interface 2 10.10.10.18


the strange things is that sometimes the interface 2 doesn't answer to the PING... but "sometimes" .... that's the strange things

I have also tried to move configuration over different virtual interface, but with no result.

It seems there is something strange related to network connection.

The "fast" workaround it has been to install a RAW new 3.0.2.5 version and configure it again...

With the new installation it is working.... but I will monitoring until tonight.
