What are the ports required for synchronization?
If you're trying to synchronize two or more web filters, make sure that the servers are permitted to communicate with each other using the following ports (TCP and UDP):
26260 26262 26263 26265 26266 26267 26268 In a synchronized environment, each web filter is allowing synchronization requests from the actual IP address of the other web filter (as determined in the synchronization setup page on each server). If you have a proxy server or firewall that changes the IP address, synchronization will fail.
