Port 80

[addvalue]

At my workplace there is a proxy/firewall and the only traffic allowed is on PORT 80.

All the addresses given are forward me to port 2095(for webmail) or 2082(for cpanel) these ports are BLOCKED at my work place.

Here is my questions:

1) why is it on these ports?

and

2) How can I set something up so it is on the normal http port 80, particulary email.

I haven't used CPanel that much, so not sure if you could change the ports. What you can do though is talk to whoevber is in charge of the firewall and see if they will just open those 2 ports at (if you haven't tried this). I can't believe they only allow port 80 traffic though.

I can believe it. I see a lot of companies that lock down their network this way, and it is becoming much more common. Many companies don't want other ports open on their firewall. After all, they are paying people to work for them, not to check their personal mail, instant message with their friends, or whatever else.

That being said, depending on the webmail program, you should be able to adjust the port settings. I wouldn't recommend doing that in cpanel as it may interfere with site performance. Another option, if you manage your own server is to set up a proxy so that if you connect to a certain domain, for instance cpanel.addvauehost.com on port 80 it will redirect the request to 2082. Your server proxies the connection for you, and you can still go out on port 80. That's the way many people get around the Instant Messenger rule.

Even then. Don't people have to check their company mail?

Try using a proxy server...

Company mail isn't likely to be on port 2095 (webmail for cpanel servers) and, even if it is on a non-80 port, it probably won't be blocked :)

Thanks! I have got an answer from the developer. He claimed that the port cannot be change and it is unlikely to as it can bind only a single service to a particular port.

Just an information in case any CPANEL user are seeking for solution.

Right, mail would generally be 110 and 25. But he siad that they blocked all ports BUT 80.

Interactive is right!

By the way, Robert, are you still looking into Perldesk? If you need the script,
let me know, will email it to you.

Well I was just looking for a Demo of it (like admin backend). But wouldn't mind :D

Most likely the mail server is on the internal network, so port 110 (or whatever mail port they are using) and 25 could be blocked to the outside (except from the mail server of course) and mail would still function fine.

Hi,

A quick work-around for cPanel servers is to just simply install your own copy of a webmail client into your own public_html directory. Squirrelmail (http://www.squirrelmail.org/) is full featured and a snap to install. You just set the config option to use IMAP with the server address set to localhost. Then you just browse to your site to check your email from any webbrowser with access to port 80

:sun:

This may not be overly helpful being on a cpanel server - however both plesk and h-sphere allow for the use of dual ports - you have the option of accessing your control panel and associated resources via a secure port (usually 8443) or unsecure (port 8080 &/or port 80) depending on the specified configuration by the system administrator...

I only mention this because Im sure something similar must be available in cpanel - though, im not overly familiar with it...

There is away around this. Someone posted a system on the cPanel.net forums which allows you to access cpanel/webmail over port 80. Do a search and you should be able to find it (it may even be still a sticky on one of the forums).

Good luck :).
