After a successful login you will reach the welcome page of the WebVPN.
From there you can change your Kerberos-password, use the VPN service
(download of the VPN client) or access to others unencrypted pages.

https://webvpn.rz.tu-harburg.de
will be displayed in the browser during the whole VPN session as the first part of the WWW-address.
Screenshot:
- Since the home page https://webvpn.rz.tu-harburg.de/webvpn/ uses JavaScript, you must allow the use of JavaScript for the address https://webvpn.rz.tu-harburg.de. In Internet Explorer for example you can add addresses to the trusted addresses under Tools/ Internet Options/ Security/ Trusted Sites/ Sites and enable the option Active Scripting under Tools/ Internet Options/ Security/ Trusted Sites/ Custom Level.

FAQ
- I get a certificate warning when I call the WebVPN page.
Install the DFN root certificate please. - Why shouldn't one conduct any sensitive activities (online-banking for example) over the WebVPN?
The WebVPN connection to the VPN terminal is a SSL encrypted connection, this certificate can be checked by the user. When accessing SSL encrypted external pages (https) through the WebVPN, the external certificates will be automatically accepted by the VPN concentrator. The user does not have the possibility to verify the validity of the external certificate. - Can I remove the WebVPN floating bar?
You cannot remove the floating tool bar nor avoid loading the floating toolbar while you establish the WebVPN session. This is because when you close this window the session is terminated immediately and when you try to login again the window is loaded again. This is the way the WebVPN sessions were designed originally. You can close the main window but it is not possible to close the floating window. - Why can my mail program pick up external e-mails with the VPN client, though not with WebVPN?
WebVPN is a web-based service, which only works over the browser with which you logged on to the WebVPN service. Other programs which access to (TUHH-) external services like e-mail or instant messenger generally cannot use the WebVPN connection. - Further answers in the general VPN FAQ.
