Hi. I'm using BM3.7 on a NW 6 server. I use this server mainly as a

firewall to force authentication to get out to the Net (HTTP/FTP
Proxy).
We also use a Pix506 combined with a Cisco1720 which are managed by an

outside source for the VPN. I'm trying to use a polycom viewstation
to
receive an IP call from an external source but it fails. If I
initiate
the call, it works fine. The external vendor has assured me that they
are
not blocking the ports necessary for this call so it must be BM. I've

tried adding an access rule that allows the NAT translated IP address(10.4.0.6) of the Viewstation to pass through any ports but still
cannot
get them to connect properly. Any ideas?
