Unhappy Ignored - Port Forward Filter - Version 8.7.3

Hello,

Not sure if I'm doing this correctly...
SecureCRT - Version 8.7.3 (x64 build 2279)


I'm trying to allow another guest to access the SecureCRT local port forwarding.

[PC (A) TELNET] -- > [PC (B) SecureCRT port 6200 ] -- > [Server Port 6200]

I have setup port forwarding from PC (B) to the server ... however from reading and testing i can see the listen port 127.0.0.1:6200. Reading I see that I will need to further modify <session>.ini and modify the following...

From:

S:"Port Forward Filter"=allow,127.0.0.1,0 deny,0.0.0.0,0
S:"Reverse Forward Filter"=allow,127.0.0.1,0 deny,0.0.0.0,0

To:

S:"Port Forward Filter"=allow,0.0.0.0/0.0.0.0,0 allow,192.168.100.155,6200
S:"Reverse Forward Filter"=allow,0.0.0.0/0.0.0.0,0 allow,192.168.100.155,6200

However testing ( and logging ) I can verify the port is only opened for listening on 127.0.0.1 and not 0.0.0.0 to allow for connections?

I also tested changing the 127.0.0.1,0 to 128.0.0.1,0 <- and the port remained open on 127.0.0.1 and did not move to 128.0.0.1 as expected. Thus from the data it seems this version of SecureCRT does not work as intended OR am I just missing configuration needed?


Working Log:
TELNET:
telnet 127.0.0.1 6200

Hummm .... Any thoughts?

Thank you.
