Proxy Tunnel Filter


You should use the proxy tunnel filter so that your server is not opened to a public access. The tunnel filter can contain only IPs, IP address masks, ports and hostnames. Sometimes you can use the same filter file for both the tunnel filter and the proxy filter.

A similar logic as for black & white filters can be applied. You can specify the default area and explicit override values (0, 1) and (0:, 1:).

Formal Syntax:

filters = *(filteritem CRLF)  
filteritem = (defaultfilter / filter)  
defaultfilter = filteraction  
filteraction = ("0" / "1")  
filter = [filteraction ":"] filtervalue  
filtervalue = ipaddress / ipaddressmask / ipbitmask  
 

Example:

1
192.168.0.1
172.16.10.0/24
www.icewarp.com
0
1:192.168.0.2
192.168.0.*
This will accept the first IP address, IPs in range 172.16.10.0-255 and www.icewarp.com as the destination host and will reject the others except the 192.168.0.2
