Hi all, i have an issue which i cannot pinpoint exactly where it is.
My setup
ISP box to Cisco switch,
from Cisco to Clearos (lets call it ClearOS1) box and servers with VMs
ClearOS1 is on separate computer virtualized and in this machine there is one onboard ethernet and additional PCI with 4 ethernal ports
i had some breaks in connections (up till 30 seconds when i pinged google) so i tried to add aditional line between cisco and machine on which ClearOS1 is located
all was working fine untill the day when i tried to put additional line from switch to clearos at the same time i switched lines for external ip from onboard ethernet to one of the 4 in PCI card
not sure what went wrong but i lost one way communication
for example i can ping Laptop1 (my laptop) from one of my vms (lets call it VM1 which has external IP) but not another way around
this VM1 has external IP and it is visible from the whole world but not from Laptop1 or any other machine in the same vlan that are behind ClearOS1
for test purposes i setup another clearos (ClearOS2, to eliminate switch issues) and if i switch Laptop1 to ClearOS2 i can ping this machine
please help, give me ideas as to what to check, cisco config or clearos config

Hi Nick
i have separate machine with proxmox and there i have virtualized clearOS1 and clearOS2
the first one has t interfaces connected
eth0 External DHCP 82.x.x.189
eth1 LAN Static 10.10.0.1
eth2 Hot LAN Static 10.0.5.1
here are outputs from
[root@gateway network-scripts]# ifconfig | grep '^\S' -A1
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 82.x.x.189 netmask 255.255.255.0 broadcast 82.x.x.255

eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

and
[root@gateway network-scripts]# grep IF /etc/clearos/network.conf
EXTIF="eno1 eth0"
LANIF="enp1s0f1 enp1s0f1.1020 eth1"
DMZIF=""

in gui i see
eth0 external dhcp 82....
eth1 lan static 10.10..
eth2 hotlan static 10.0.5..
and after i removed those enp1 (those were physical prots on this 4 port network card)
my network.conf looks like this
# Network mode
MODE="gateway"
# Network interface roles
EXTIF="eth0"
LANIF="eth1"
DMZIF=""
HOTIF="eth2"
# Domain and Internet Hostname
DEFAULT_DOMAIN="digriz.eu"
INTERNET_HOSTNAME="gateway.digriz.eu"
# Extra LANS
EXTRALANS=""
# ISP Maximum Speeds -

hi Nick
all is fixed so i think that what you recommended has worked it just needed a little time to work
yes i removed those extra devices
when i created this clearos i installed clearos on new VM and backed up the old one and put it into new one
the old one had those physical NICs and they stayed in the network.conf
i removed them and problem is gone
thanks for help -
