1. HTTP filter ignores gzip webpage
In HTTP filter module, web keyword filtering function can automatically recognize ANSI and UTF8 coding and perform keywords matching. However, the web keyword filtering is overlooked when some web servers use gzip to output compressed webpage content, which cannot be recognized by HTTP filter module

2. Shortage of passby mode
When using a passby mode in LAN. Limited with the network topology, Active Wall can not deny UDP/ICMP/IGMP packets. Several filtering modules do not work. If the option [Enable active redirect on passby mode] is checked, Active Wall will start the function ARP spoofing, which will redirect all the data packets in LAN. It is recommended that the ARP spoofing function is used only in small-sized LAN, for the reason that this function does some impacts on performance of the whole network.

3. Delay of domain filtering module
When a computer in LAN tries to analyze a domain name, it will firstly search in local host DNS cache. If it can find the domain name, it will return at once. Or it will send a DNS query request. So a new policy on DNS filter module may not work at once on the monitored computers. After the local host DNS cache expires, the policy will work.
