MN-700 Netmeeting probs despite DMZ

Netmeeting on the machine in the DMZ can be called by its router's WAN
IP. But this is a T.120 data call only - no audio/video in neither
direction.

The same DMZ machine can put an outbound call to the WAN IPO of a
dialup machine. This establishes T.120 and audio/video. But
audio/video is one-way only: only outgoing a/v is received by the
remote partner, but no a/v is coming in.

The router's firewall settings seemingly cant be modified.

The settings of the personal firewall are no obstacle, since the same
machines do fully functioning calls and two-way conferences, if the
router is turned off and they use dialup connections each.

Any idea for at least a partial improvement?
