        Yeah dude are you running a proxy with user auth?  You clearly can not talk to your ldap server..  You clearly have an issue with your clock being off.. That could cause all kinds of problems..  Because it doesn't say error sending traffic your just going to not think it has anything to do with your problem??

        why would your wan be in a bridge in the first place??  Did you upgrade kvm?  Did you upgrade pfsense?  There are all kinds of issues with pfsense 2.2 and kvm.

              Dude I see 198.50.221.177 pinging 198.50.221.190 every second and working.. That is your wan apinger I would gather..  What are you lan rules?  Did you sniff on your wan to see if those pings to 8.8.8.8 got forwarded?  Did they get a reply on your wan and just not seeing it back on your lan?

              KVM has known issues with pfsense 2.2 - what version of kvm are you using.  Are you using any packages?  Proxy for example - why don't you fix your errors.. Why did you clock go backwards?  why can you not bind with your ldap server??  etc. etc. etc…

                Yes, I added to hosts file entry for ldap and restarted ntp. To make log clear.

                        "I want make sure IPS is will protect it."

                        What???  So your running SNORT?  So maybe that is blocking your traffic.. When did 2.4 of pfsense come out??  2.2.4 is latest..

                        Its a VM right - why don't you just load last snapshot or deploy base install again..  And again a KVM has known issues with pfsense 2.2 and above

                                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
