Chapter72 Configuring Clientless SSL VPN
Application Access User Notes
Do nothing—Application Access does not start. The remote access home page reappears.
Delete backup—Clientless SSL VPN deletes the hosts.webvpn file, leaving the hosts file in its
clientless SSL VPN-customized state. The original hosts file settings are lost. Application Access
then starts, using the clientless SSL VPN-customized hosts file as the new original. Choose this
option only if you are unconcerned about losing hosts file settings. If you or a program you use
might have edited the hosts file after Application Access has shut down improperly, choose one of
the other options, or edit the hosts file manually. (See “Reconfiguring hosts File Manually.”)
Reconfiguring hosts File Manually
If you are not able to connect to your remote access server from your current location, or if you have
customized the hosts file and do not want to lose your edits, follow these steps to reconfigure the hosts
file and reenable both Application Access and the applications.
Detailed Steps
Step1 Locate and edit your hosts file. The most common location is c:\windows\sysem32\drivers\etc\hosts.
Step2 Check to see if any lines contain the string: # added by WebVpnPortForward
If any lines contain this string, your hosts file is clientless SSL VPN-customized. If your hosts file is
clientless SSL VPN-customized, it looks similar to the following example:
server1 # added by WebVpnPortForward
server1.example.com invalid.cisco.com # added by WebVpnPortForward
server2 # added by WebVpnPortForward
server2.example.com invalid.cisco.com # added by WebVpnPortForward
server3 # added by WebVpnPortForward
server3.example.com invalid.cisco.com # added by WebVpnPortForward
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 cisco.example.com # source server
# 38.25.63.10 x.example.com # x client host
123.0.0.1 localhost
Step3 Delete the lines that contain the string: # added by WebVpnPortForward
Step4 Save and close the file.
Step5 Start clientless SSL VPN and log in.
The home page appears.
