PIX Stateful Firewall Feature

Unanswered Question
Jan 8th, 2009

Hai everybody,

I have a problem with my PIX 535 with its Stateful filtering configuration.

We are having Cisco IP phones on its two different zones and Cisco Call Manager on one of this zone.

I had to open up a hell lot of ports for the IP phones to communicate between the zones. The ports i have opened up include SCCP-TCP 2000[skinny protocol], tftp-UDP 69, udp ports 16000-60000 etc.

Don't the Firewall need to open up these ports based on its stateful firewall capabilities.

Please guide me about the ports that need to be opened for communication between Ip phones with Call manager and Video conferencing solutions.

For your info, i don't have any Global service rule policies configured in our PIX Config.

Thanks in advance.

I have this problem too.
