Pandoras Box > Ports Used by PB and WD

This chapter lists all ports used by Pandoras Box and Widget Designer that are of interest when setting up a firewall or network router. Most ports are used for TCP and UDP unicast packets unless it is specified otherwise in the table. Please make sure that our multicast communication is not blocked.

If you are using configurable switches and would like to use IGMP Snooping, make sure that ALL switches in your network are configured accordingly. Otherwise, IGMP Snooping can be deactivated as well.
