Configuring the Contivity VPN Client
Chapter 2
Customizing the client
This chapter provides information to help you customize your client, including
configuring client profiles, creating custom icons and bitmaps, and distributing
the custom client installation. You can also reconfigure client behavior and
control the client from a third-party application.
The Contivity VPN Client supports dynamic DNS registration, which you can
configure at the group level on the Contivity gateway. The Contivity VPN Client
also provides support for IP Security (IPsec) mobility and persistent tunneling.
Table 2 shows the versions of the client that are available in limited (56-bit) or full
(128-bit) form, as well as the available encryptions, Diffie Hellman groups, and
hashes.
