Hi,

    Can you provide more insights in what is your configuration? This
seems like a network issue.

    Do you have IDS (snort) turned on?

    Is it virtualized or installed on a bare metal?

    Please try to provide captured traffic using the next syntax:
tcpdump -s0 -nnvv -i br0 -w GREEN_capture.pcap

    Choose `-i' for the interface you are experiencing downtimes.

    Check also /var/log/endian/uplinks and see if the main uplink goes
offline/online from time to time.

    Make sure that also your ISP is not causing problems.

    Also some dumps of your Firewall rules would be interesting since
you mentioned you can't ping it.

    You can dump them with this:

    for table in "filter nat mangle security"; do echo -e
"\n\n[--$table--]" ; iptables -t $table -nvL | curl -F "sprunge=<-"
http://sprunge.us; echo ; echo ; done

    Return the links you get, they will expire in a while.


    Is this issue 'felt' from your LAN (just asking that maybe you're
a mobile user connected to it via VPN and trying to ping it over a
public network like the Internet)?

Cheers,
Alex
