Anyone out there using NetMeeting to go across the firewall? It seems like
for NetMeeting 3.0 and above, it now uses QoS packets and is sending IP
protocol RSVP packets with IP Option 148 (RTRALT - Router Alert[RFC2113])
set during the conversation.
Everything seems to be fine to the two parties talking - they get video,
audio etc., but the firewall drops these packets with the IP Option set in
Rule 0.
So my question is: Because FW-1 automatically drops packets with any IP
Options set - is FW-1 preventing us from "doing special things" by not
having these programs that are using IP Options (such as Qos stuff) use
those packets?
I understand that the reason FW-1 automatically drops these packets is
because it assumes that if a packet has an IP Option set, it's dangerous -
so does that mean that if you're using FW-1 you are being denied from doing
things like QoS, etc. Has this topic been discussed somewhere else before?
Has anyone else seen this on their firewalls? Do I just ignore it or can
something be done with NetMeeting to prevent it sending these out? Do I even
care?????
Thanks,
Karen
