Unable to open port 30000

Post by datona »

Has anyone had problems with opening port 30000 to be used with Canada Post's shipping module?
I have the following in my csf.conf file but the port is not opened:

TCP_IN = "20,21,22,25,26,53,80,110,143,443,465,587,993,995,2077,2078,2082,2083,2086,2087,2095,2096,3306,7630,30000"
TCP_OUT = "20,21,22,25,26,37,43,53,80,110,113,143,443,587,873,2086,2087,2089,2703,3306,7630,19638,30000"
TCP6_IN = "20,21,22,25,26,53,80,110,143,443,465,587,993,995,2077,2078,2082,2083,2086,2087,2095,2096,7630,30000"
TCP6_OUT = "20,21,22,25,26,37,43,53,80,110,113,443,587,873,2086,2087,2089,2703,7630,30000"

Did you restart the firewall with csf -r ? We don't have any issues with Canada post. Also you don't need to add it to UDP only TCP is required.

Check to see if its opened:
# csf --status | grep 30000

Yes, I did restart CSF afterwards.
When I ran that command, this is what I got:
csf --status | grep 30000
38 3 180 ACCEPT tcp -- !lo * 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:30000
64 0 0 ACCEPT tcp -- * !lo 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:30000

But when I attempt to perform a port check on 30000, I get closed.

I am wondering if there would be a conflict due to passive FTP

The ports are open correctly on the firewall. See if you can connect manually using openssl:
# openssl s_client -connect sellonline.canadapost.ca:30000

You should get a CONNECTED(00000003) if it is working correctly.

Then your issue has nothing to do with the firewall. You wouldn't be able to connect if the port was getting blocked. The firewall is working correctly.
