Hi,
I would like to know how to open port 20/21 to our Cisco router 881, I'm a new hire and just new to Cisco router.
Here are the details
Local static IP address 192.168.1.161
Public IP Address 119.75.32.114
I need to open the port 20/21 to access the FTP server outside.
I ran a port test for port 21
Success: I can see your service on 119.75.32.114 on port (21)
Your ISP is not blocking port 21
I ran a port test for port 20
Error: I could not see your service on 119.75.32.114on port (20)
Reason: Connection refused
Now even port 21 is open I can access the FTP site
I created the FTP server using IIS 7
Please assist.
I tried the following but didn't work.
ip ftp username xxxxx
ip ftp password xxxxx
no ip ftp passive
ip ftp source-interface fa4
