URGENT HELP libvirt kvm

Well you have it enabled and not running - so like blocking everything? Why would you have to add a host file for ldap – wasn't it working before?
So that sniff showing pings going out to 8.8.8.8 was on your wan?? Then why was it showing your 10 address then as source - that for sure would never freaking work.
Here is me sniffing on wan for ping of client to 8.8.8.8 see how source is my public IP..
That sniff made no sense to me - if on lan why was it showing what looks like your apinger every second.. But private IP pinging 8.8.8.8
You had errors in your log about NAT as well.. Not installing nat reflection.. Seems to me you got ALL kinds of problems for something what was working yesterday.. Snort not running, time off, can not resolve your ldap server, rules not loading? traffic going out wan with private addresses..
-
That sniff make perfect sense that point the issue is bridge0 interface, because from pfsense him self I can ping both ends LAN and WAN. Arp ping you see as I says, because pfsesne can reach ISP provider side no problem. That indicate that some issue on BRIDGE0 interface which cause traffic do not to be forwarded from LAN to WAN. I can share my screen and you can see.
Host file entry need for ldap because encryption port 636 where ldap server validate the CN. And each time I am reboot pfsesnse it override /etc/hosts and connection to ldap is failing, I could't find how to preserve this entry in host file. If IPS down and it not blocking traffic. -
How does that sniff make sense?? You can see pings from public ip to public IP working - sourced from a 10.x to public IP 8.8.8.8 not working.. As it shouldn't how exactly is 8.8.8.8 going to answer you from a 10 address?
You stated you sniffed on pfsense WAN.. If that is the case it should be showing you WAN IP pinging 8.8.8.8 not some 10 address.
How exactly do you think this would work??
-
Because it hit bridge0 interface and Outbound NAT is not applied and connection Outbound from LAN to WAN that why it show private ip. Secondly LAN subnet is directly connected to pfsense it will never show you in packet capture applied NAT rules. If you sniff traffic on WAN interface and it will be inbound connection then you should see PUBLIC ip's.

That exactly what I am says Bridge0 interface not working !!!!!!!!!!!!!!! PFSense not FORWARDING TRAFFIC FROM PRIVATE SUBNET LAN TO PUBLIC INTERNET

By The way Snort fail to start. I just updated to last package. Here the log for Snort start up.

Dude, when you don't have absolutely basic shit working, why are you mesing with Snort? (Totally OT here in addition.)
-
True Agree. I am focusing on issue of BRIDGE0
-
Here are TCP settings. I disabled offload as was recommended, but result the same.
-
I was thinking what else can be. I did tcpdump on virtual host him self Fedora Server and still see private IP, which I though on this stage I should see only public ip, because pfsense should apply outbound NAT rules. What else I can check.
[root@dedi132 ~]# tcpdump -i any -vvv -nnnn -s 0 icmp 16:32:24.378774 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.18.130.50 > 8.8.8.8: ICMP echo request, id 40991, seq 641, length 64 16:32:24.378782 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.18.130.50 > 8.8.8.8: ICMP echo request, id 40991, seq 641, length 64 16:32:24.378900 IP (tos 0x0, ttl 63, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.18.130.50 > 8.8.8.8: ICMP echo request, id 40991, seq 641, length 64 16:32:24.378909 IP (tos 0x0, ttl 63, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.18.130.50 > 8.8.8.8: ICMP echo request, id 40991, seq 641, length 6 -
"Secondly LAN subnet is directly connected to pfsense it will never show you in packet capture applied NAT rules. If you sniff traffic on WAN interface and it will be inbound connection then you should see PUBLIC ip's."
What??
I assume its wan is 198.50.221.177, pretty sure in fact that is your pfsense since when I hit it I get pfsense login! That you have webgui allowed on your wan is just another F'd up thing with this setup that is for sure
why don't you PM me a login and I will take a look directly to what is going on.. What kind of BS setup do you have that devices on the lan side of pfsense would not be natted through pfsense wan?? I can tell you for sure yes you would see natted traffic on the wan and on the lan you would see the non natted traffic. So as you can see here is me pinging you on the lan interface of pfsense where it shows my private address, and there it is going out the wan with my public IP. And you can also see pfsense pinging its gateway every 1 second as it does with default apinger running.
-
Not sure why it working from WAN, I don't see any rules which will allow the access.
-
Look like firewall is not running. Logs are from Sat 5 midnight. That why you can access it.
-
Check screenshot from PFSense where on tcpdump I am capture traffic on BRIDGE0. Server on LAN is send ping, but nothing coming back. look like firewall not running or something like that.
-
show the same capture but on pfsense WAN (not bridge0)
-
BRIDGE0 is the WAN
-
In first my post I have small schema design.
-
ok, just read the thread again. Your setup looks messed up.
no other suggestion apart from restore from backup. :-) -
I think it some thing to do with firewall. Logs in web UI is not writing still from midnight Sep 5.
-
well its not pinging now.
