PIX PAT and NetMeeting

[m.colon]

I am trying to get netmeeting working through our Pix. We are currently doing PAT. I know that this will be a problem. Will the established command solve the problem?

NetMeeting is an application that uses the H.323 voice over IP protocol. It uses tcp port 1720. The "fixup protocol ils" command provides NAT support for Microsoft NetMeeting, SiteServer, and Active Directory products that use LightWeight Directory Access Protocol (LDAP) to exchange directory information with an for Internet Locator Service (ILS) server.

PIX Firewall software versions 6.2 and higher support PAT for H.323.

Also use fixup protocol h323.

Hope that helps.
