Business to Business Connections

Enterprise A Client

The Collaboration Server can be configured to send a FW NAT keep alive message at specific Intervals

for the RTP, UDP and BFCP channels.

This is necessary because port mappings in the firewall are kept open only if there is network traffic in both

directions. The firewall will only allow UDP packets into the network through ports that have been used to

send packets out.

By default the Collaboration Server sends a FW NAT Keep Alive message every 30 seconds. As there is

no traffic on the Content and FECC channels as a call begins, the firewall will not allow any incoming

packets from the Content and FECC channels in until the Collaboration Server sends out the first of the FW

NAT Keep Alive messages 30 seconds after the call starts.
