After installing the Zoo, you need to ensure that TCP Port 80 is open for both incoming and outgoing communications in the firewall software running on the Zoo server system. So unless they relax their firewall restrictions, you're going to have to do something like use your cellphone as a dialup modem to access those mail accounts, or use webmail (since they probably aren't blocking all http (destination server) port 80 traffic - although they could be blocking traffic addressed to specific host addresses like /webmail). Zoo communicates with Rhino clients via TCP Port 80 (HTTP). They would be blocking this at their firewall to the internet.

Your problem, most likely, is that your IT Dept is blocking outbound traffic destined for any "foreign" host addresses at ports like 25 or 143, that are NOT the host addresses of your IT Dept's own mailservers. , 80, etc.) port to the random port number that your application chose. The (mail, web, other) server responds back from its port (25, 143. Safari, port 80 refers to the web server, not what port on which you are sending out your browser request to the server. Same holds true for all applications, e.g. If you launched Terminal.app, "su " and "sudo tcpdump -i en1" (en1 if wireless, en0, if ethernet cable) you will find that when you launch Mail and try to check mail or send mail, stuff from your computer is leaving your machine on a randomly chosen (by Mail.app) five-digit port number and it's at the destination server where these port numbers (25, 587, 465, 110, 995, 143, 993) have any meaning. Plus, in Mail.app (or any other application for that matter), those port numbers (like 25 or 587 or 465 for smtp, or 110 or 995 for pop, or 143 or 993 for imap) are at theĭestination mailserver, not your computer. But you're not a server, you're a client. Opening ports there is only for dealing with inbound traffic that you didn't initiate and weren't expecting as a response to something, i.e., if

In this tutorial, you have learned to open port access to all traffic or specific IP address/network using firewalld on Linux operating systems.From the client side, you don't need to open any ports in Sys Prefs Sharing at all. Next, run the following command to apply the changes: firewall-cmd -reload Conclusion If you don’t need to keep the ports open, you can remove/deny the above ports from the firewalld using the –remove-port option: firewall-cmd -permanent -zone=public -remove-port=3306/tcp The last line of output shows the rich rules added the firewalld. firewall-cmd -reload Verify RulesĪfter adding the rules in firewalld, You can verify the by the running following command. Reload the firewall rules to apply changes. firewall-cmd -permanent -zone=public -add-rich-rule=' Run the below command to allow access for port 4567 to 192.168.0.0/24 network. To open port access based on source address needed to add firewall rich rule.

You can also restrict access on any port based on source address. firewall-cmd -permanent -zone=public -add-port=3306/tcp Allow Port for Specific IP To add rule for permanent use -permanent option with command. firewall-cmd -zone=public -add-port=3306/tcp Use the following commands to allow incoming traffic on port 3306 to all traffic coming from public network. You can use the same command for any other ports as per your requirements. In this tutorial, all the commands are written for MySQL port 3306. The -z option tells nc to scan only for open ports, without sending any data and the -v is for more verbose information. Find our previous article about installation and uses of Firewalld on Linux system. For example to scan for open TCP ports on a remote machine with IP address 10.10.8.8 in the range 20-80 you would use the following command: nc -z -v 10.10.8.8 20-80. This tutorial describe you to open a port for public, specific IP or IP range in firewalld.
