    nope. please deposit .25 to play again 3CX documentation states that KVM 2.8 and above are supported. there are several products that build on top of kvm, proxmox, virtuozzo and others. These are NOT replacements for KVM but are WebUIs. The underlying technology is still KVM. This...

    yup, and if you look it's the same root@3cx:~# ifconfig ens18: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.1.13 netmask 255.255.255.0 broadcast 192.168.1.255 inet6 fe80::4872:d1ff:fe19:fd9d prefixlen 64 scopeid 0x20<link> ether 4a:72:d1:19:fd:9d...

    I dont see anything wrong with the network config I posted, however I'll post again using ifconfig and route instead of the newer IP2 tools root@3cx:~# ifconfig ens18: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.1.13 netmask 255.255.255.0 broadcast 192.168.1.255...

    ok, I have stumbled on to the solution. 3CX does not support virtio. I dont know what 3CX is doing under the hood, but virtio is out Virtio: DNS - ok ping - ok telnet - ok wget - ok 3CX firewall checker fails on all tests but DNS Switching to E1000 adapter and the firewall checker passes...

    yes and i posted the routing table above, I also posted that ping, wget and telnet are all working just fine both inbound and outbound.

    every linux system I have ever encountered lists lo as the first interface, even on bare metal. why 3CX and only 3CX is using the lo interface is a 3CX problem. Additionally since your supported hypervisors include KVM 2.8 and up since proxmox is just a GUI on top of KVM, then I would say I...
  8. firewall checker

    proxmox is a well known hypervisor running on debian based on KVM. I have another proxmox hypervisor with a 3CX guest running with no problems. While it is possible that the hypervisor is causing problems, I kind of doubt it because all other network communications are working without issue on...

    yes, it was deployed on proxmox host, using the 3cx iso and guided install debian-amd64-netinst-3cx.iso
  10. firewall checker

    Other traffic I have checked routes out correctly (ie: ping, wget http://www.google.com, telnet stun-us.3cx.com), so if the firewall checker is using 127.0.0.1 it has nothing to do with my network config or firewall config. What else should I be looking at?
  11. firewall checker

    not sure what else to check other than these settings: root@3cx:~# ip a s 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever...

    I filtered with dns and classicstun only connection is from localhost to localhost
  13. firewall checker

    here are the results. never tries 3478 I can't upload the dump, but I can throw it on my drive if that is permissible
  14. firewall checker

    so why doesn't the firewall checker even attempt to make a connection to any of the servers or ports? as was explained in my previous post tcpdump shows no attempts made. No connection requests ever leave 3cx and how can the checker be run with more debug info? if it doesn't even attempt to...
  15. firewall checker

    just adding a few more details, I rant the test twice, once capturing all traffic to any of the IPs for STUN and ALG test servers. The second time capturing any and all traffic on port 5060 or 3478. No data was ever captured. Other than the DNS traffic I see nothing else root@3cx:~# tcpdump...
  16. firewall checker

    can the firewall checker be run on the command line with more verbosity? I'm getting pretty much complete failure with it. packet capture is run on 3cx and on the firewall internal and external interfaces packet capture shows that stun and alg servers are being resolved, but I never see a...

    V15.5.1694.0 We have a SIP trunk with 6 DIDs. The DIDs are provisioned with COX so that if our PBX doesn't answer they automatically roll to an answering service. 3CX is configured so that during business hours any calls are sent to a ring group which if not answered goes to IVR. After hours...
