open ports required for NAT CS5000 - 10/02/13 03:15 PM
Hi
I'm having a nightmare trying to get two way audio from our inter-tel cs5000 to a remote endpoint.
The remote endpoint is currently on a public IP for initial testing of the NAT on the local firewall. It can find the CS5000 and make calls. I can hear audio from the phone thats's inside the firewall, but no audio from the remote endpoint.
Looking at the nat translation table on our cisco router, I'm finding that the expansion card IP address is trying to make udp connections outbound on a variety of port numbers from around 6000-8000. The processor module IP is handling the TCP outbound connection on 5566.
I've tried changing the endpoint NAT through auto/nat/native but it makes no difference. Does the whole system need powercycled after this is changed?
Looking at the inbound acl on the firewall, the remote endpoint does not try and send any udp packets to the processor module natted IP.
Will this system even work without a VPN connection? The expansion module address trying to make outbound connections has thrown me a bit.
Sorry for the length of this
