An H.323 proxy could solve these problems. Firewall-1 states they
can
handle H.323 and work with Netmeeting (Does anyone have any
experience
with this?). Guantlet/NT has an H.323. proxy but theiradministrator'sguide, which lists several multimedia applications, does not list NetMeeting. Are there other firewalls that can handle netmeeting?Cisco PIX has the ability to securely convey H.323 (including MS NetMeeting),Does the same apply for the Cisco IOS firewall feature set?
Not quite. While the IOS firewall feature set does stateful filtering for many application protocols (i.e. beside keeping the state of transport layer stuff it knows how applications work on network and transport layer) *INCLUDING H.323* it will (IMHO) not do network address translation on many of those protocols that embed IP addressing information above the network layer (prime examples include FTP, NBT, SQL*net and most multimedia, again including H.323). Cisco IOS NAT (also in the FW feature set) supports FTP, but not other protocols when translating addresses. The PIX supports more or less everything with NAT. If you have more Cisco-specific questions I suggest we take this thread off the mailing list. Best regards, Jan
