The VPN connection failed due to unsuccessful domain name resolution when I entered the domain name of router's interface g0/1 from nslookup (server 8.8.8.8). Updated2: I could do forward nslookup but reverse lookup (domain name - IP) returns failed. Is it a problem? Update3: In router's config: ip name-server 8.8.8.8.

However, you may be able to configure your system to connect to the Virtual Private Network (VPN) server if your system offers a compatible VPN client.
To construct your own VPN connection method, you should configure your VPN client as follows:
- VPN server: vpn.illinois.edu
- Username: Your NetID
(or, if you're a guest, your guest ID) - Password: Your Active Directory password
(or, if you're a guest, your guest password) - Group: 1_SplitTunnel_Default
(Note: This is the most common choice, but you may want the Tunnel All profile for Library access. See About VPN Profiles for information about the alternatives.) - Authentication Domain Name: none
- On some Linux variants, you may need to add additional configuration information:
Refuse 40-bit encryption
Require Microsoft Point to Point Encryption [MPPE]
These guidelines are available for reference, but you will need to work out the configuration of your own system and its VPN client.
Travelers: If you have another Cisco VPN software client installed on your computer already, you may be able to connect to the University VPN server using a guest account and that software.
