I set up A FTP service internally, want to provide services, trying to test (not through the firewall equipment), everything is normal, but when to address translation, found that the network can pop-up account password, but can't visit, prompt type set in 200 A, 501 server always accept A argument.
Inside my configuration:
1 address translation purpose transformation area: OUT telecom address: 61. *. *. * txjftp60002 purpose: 192.168.11.31 service: FTP
Here is 61. *. *. * port 60002, converted into 192.168.11.31 21 port, visit,

2 access control policy: all OUT telecom address: 192.168.11.31
Allow all telecom over the flow of data access 192.168.11.31 port,

Baidu to see a lot of to open 1-65535 port can solve, here I don't know how to open all port 1, 2 opened nor safe,

Personal feeling is visited 21 after the port, the port of data transmission in the transformation problems,
