Jabber client behind firewall and proxy
There is a great article explaining how to setup jabber client to connect to jabber server which is outside firewall: https://web.amessage.eu/firewalled
Behind the scene, if your jabber server don’t support connection through 80/443 port, then you can:
- register new account on jabber80.com
- Most of the desktop clients support automatic account registration.
- install a client that support proxy connection (vacuum-im, psi)
- manage a account to connect through proxy (need to know the company proxy)
- use jabber80.com:443 as a server to connect to.
The company I work for uses firewall that block everything besides HTTP :80/443 and proxy to manage outside connection.
I succeed with setup my desktop client to jabber.wp.pl and talk.google servers.
talk.google
The configuration for google talk is as follows (for vacuum-im):
- set your credentials (username@gmail.com)
- enable and configure the proxy server (the one you use to connect to internet)
- tick “Use legacy SSL connection”
- manually set the host: talk.google.com port: 443 or 80
There is also solution with proxytunel, described here. I didn’t try this.
Left with
Since I normally don’t use google account, and my primary jid is at jabber.org; I was forced to use my previous solution - jabber web client which is bundled into mail service I use (zoho.com). Generally all web clients works fine (assuming the proxy is configured correctly).
