Necessary to open ports on VE's somehow?

[jamesd256]

Hi,

How do we control what ports are opened on the VE's

Using the Ubuntu 8.04 appliance, I find that only ports 80 and 22 are open, and there do not seem to be any firewall rules in operation.

Thanks,

James

Proxmox VE has no firewall by default. Its recommended to install a hardware firewall.

But its worth to search this forum, a lot of users managed to get a simple firewall working.

The trouble is, I have installed JBoss server in a VE, and while port 8080 is listening locally, it is not open to connection from outside the VE, even from the HN.

Thanks.

I will answer my own question, as it is now clear what is going on.

By default, it seems that Jboss looks for the first interface to bind to and in our case, it finds venet0, so it binds to 127.0.0.1. So we have to use the -b parameter and specify the bind address of the external interface.

The exact same situation occurs with mysql, but both are now available externally.

Thanks.
