How do I modify port-forwarding filters in SecureCRT®?

SecureCRT has filters that control who can connect to port forwards that have been set up in SecureCRT. By default, only connections coming from the machine that SecureCRT is running on can connect to the port forwards.

You can change the port-forward filters by following the steps below (make sure SecureCRT is not running at all when you attempt this):

1. Find the .ini file associated with the session that you want to modify. The .ini files are located in the SecureCRT Config folder under the subfolder called Sessions. The Global Options dialog also displays the location of the SecureCRT Config folder in the "Configuration folder" field.
   
   
2. Open the .ini file in Notepad.
   
   
3. Look for the following line:
   
   S:"Port Forward Filter"=allow,127.0.0.0/255.0.0.0,0 deny,0.0.0.0/0.0.0.0,0
   
   
4. Modify the line to read as follows:
   
   S:"Port Forward Filter"=allow,127.0.0.0/255.0.0.0,0 allow,xxx.xxx.xxx.xxx,0 deny,0.0.0.0/0.0.0.0,0
   
   Alternately, you could modify the line to read as follows allowing any IP address to connect to the port forward:
   
   S:"Port Forward Filter"=allow,0.0.0.0/0.0.0.0,0
