Symptom: Filters page loads more than 1 minute due to huge json file generated when big range of ports used in the filters. For NFCU customer scenario we see that the bigger range is problematic but is not the main cause. When customer has a filter which is comprised of UDP ports ranging from 2048-65535 and if it is UDP source and destination port the filter screen is completely frozen and never loads and will lock up NDB. Seems to be more an issue of having both source and destination (bidirectional) with that larger range than just the larger range. Along with filters page, editing/modifying connection also does not work. Conditions: big number of ports used in the filters leads to slow down of GUI and bidirectional UDP filter with 2048-65535 range causes it to completely lock up and not load.
