I am using the 3COM Office Connect Firewall 25 for network protection. I can set a rule to allow H.323 and T.120 traffic through, but it still fails with Netmeeting. The problem is the dyamically assigned UDP ports that Netmeeting uses for audio. Unfortunately there is no way that I can find to pass a large block of port numbers. As a temporary fix I am running dual NIC's in my computers with one of them downstream of the firewall and the other connected directly to the Internet router. Netmeeting traffic is handled though the WAN side NIC. I am running BlackIce to protect the computers that have connections upstream of the firewall. This all works fine 99% of the time, but there are two random errors that pop up during Netmeeting sessions: 1. The firewall will occassionally report "IP Spoofing" listing the WAN side NIC as the source. 2. BlackIce will occassionally report "ICMP flood" listing the IP of the person I am talking to as the source. Any idea why this might be happening? _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com ----------------------------------------------------------------------- http://www.meetingbywire.com/Mailinglist.htm for unsubscribe information -----------------------------------------------------------------------
