Special networking options?

Hello, I recently upgraded a couple Asterisk servers to proxmox 2.2 (with all updates) runnning CentOS 6.x in an openvz container. The process went extremely well and everything has been working great for a few weeks with the exception of IAX trunks. Initially they worked fine from V to V and V to P but after a week or so of uptime to V to V went down and then two weeks later the V to P. I have found nothing to bring them back up and have had to convert to SIP trunks to keep communications going. Interestingly, IAX connections to locally provisioned iaxmodems are not failing! I am using virtual ethernet (eth0, eth1 , etc) in the container. IAX uses UDP port 4569 standard. I've made no special adjustments to /etc/sysctl.conf beyond enabling forwarding.

As anything off the container is dropping so it makes me wonder if there is some special networking permissions / provisioning I need to do with the container. Does anyone know of such a thing?

Thank you, Andy
 
Just to follow up, I was able to fix the connection by changing the configuration from host=<IPADDR> to host=dynamic and adding a registration string. The original configuration I used had been fine for years in a physical environment but for whatever reason, failed in virtual.
