Filter Reload breaks ip-telephony connections

lordarcane

Hey

I am totally satisfied with PFsense, though I have one questions with the functionallity that still bothers me. My company have about 30 iptelephones wich traffic gets routed through the pfsense, and further through a vpn to a remote location. "Ordinary" data traffic also passes through the pfsense gateway to the same location.

When I make some changes to the pfsense setup and applies them so that the filter reloads, all the calls that are connected to the iptelephones breaks. Ordinary streams seems to be unnafected, or maybe it is that it goes unnoticed for the apps. But, the phones looses the connection to the caller.

Ip telephone connections seems to be much more sensitive to the filter reload process. Is there any way around this? Are the problem known? For now I have to make changes on off times so to speak.

I´m running PFsense 1.2.2

Greatful for help!

You might try the changes suggested in option #2 here:

It's possible that the entries are expiring too fast in this case and the calls are dropped.

Thank you! I will update to 1.2.3 and try that out! Let you know how it went.

Hello! And, thankyou again for your suggestion. I have update to pfsense 1.2.3 and tried option #2 but no success.
Still when i for example add an firewall rule or the like and press apply, the iptelephony connections break, simultaniosly on all the phones. Network seems ok though.

Any other hints?

I will try to explain more about our setup, since this problem continues to bug us.

Network Setup

WAN
PfSense
LAN > VPN > Remote site with IPTelephones (H.323)

The gateway to our remote site has the pfsense as its internal default gateway.

So, all traffic from our remote site passes through the VPN , then to the pfsense and from the pfsense out. I´ve tried to find the iptelephones ipnumers in the state table, but they dont seem to be there.

When we for example changes a static route on our pfsense, the filter reloads and the calls on our phones on the remote site breaks.

The telephone system is Solidus Ecare on a MX-ONE telephone system and really has nothing to do with the pfsense itself, only that the clients on the remote site speaks through the pfsense to our telephony systems.

The clients seem to bee unaffected otherwise when the filter reloads. They maintain communication to all the systems. Only the iptlephones traffic breaks.

Any comments tips or the like is much appreciated.

Best regards
