8. Since BWM has been activated in system default configuration, please remember to turn off

Design Limitations:

Note: These design limitations will be removed on next release once it is created into announced

knowledge base.

Anti-Virus

1. [SPR: 070813118]

[Symptom] ZyWALL has the limitation on concurrent sessions for ZIP and RAR

decompression. If the limitation has been reached (typically in HTTP traffic), the event would

be logged and the action depends on the checkbox (Destroy compressed files that could not be

decompressed) is checked or not. If checked, compressed files would be destroyed, otherwise,

bypassed.

[Workaround] Unchecked the option of “Destroy compressed files that could not be

decompressed” in the AV settings.

2. [SPR:100408336 ]

[Symptom] DUT can’t detect Virus if the compress file includes virus file and encryption file.

And the encryption file is list as first in the compress file. This is our design issue that AV will

ignore detection when encounter encryption file.

3. [SPR: 111027822]

[Symptom] AV black/white list functionality abnormal with special HTTP URL(such as

http://1.1.1.1/download/?command=download&filename=abc.zip)

[WORKAROUND] Add wildcard rule “*abc.zip” to support this case

Build in Service

1. [SPR: 061208575]

[Symptom] If users change port for built-in services (FTP/HTTP/SSH/TELNET) and the port

conflicts with other service or internal service, the service might not be brought up

successfully. The internal service ports include 10443/1723/2601-2604. Users should avoid

using these internal ports for built-in services.

[Workaround] Users should avoid using these internal ports for built-in services.

2. [SPR: 100419981]

[Symptom]DNS doesn’t resolve 2nd level domain name.

Example:

System-＞DNS-＞Address/PTR Record, add two record

1 2 3 4 5 6 7 8 9 ... 75 76
