Netmeeting traffic outside to inside on PIX

Hi

I want to setup netmeeting from the outside to the inside interface on a PIX 515E 6.1.(4). Our PIX is setup without any NAT.

Which ports do i need to open?

Re: Netmeeting traffic outside to inside on PIX

Here are the ports:

389 Internet Locator Server [Transmission Control Protocol (TCP)]

522 User Location Server (TCP)

1503 T.120 (TCP)

1720 H.323 call setup (TCP)

1731 Audio call control (TCP)

According to this article:

(check the date on the article to make sure it is current)

HTH,

Ok, thanks.

How can i solve this without opening the entire udp range? I suppose fixup doesn't work from outside to inside.

Pass through secondary UDP connections on dynamically assigned ports (1024-65535).

You don't need to open the entire udp range. Just permit the above ports on the acl.

As far as I know, from the ports above, only H323 fixup is supported and it works from outside to inside.
