Advanced settings:

The Cisco AnyConnect VPN client requires an SSL tunnel (TCP port 443) and optionally a DTLS tunnel (UDP port 443).

VPN clients contact the VPN servers in the netblock 192.76.7.64/27.

VPN clients will be given an IP address from the private IP ranges of 10.1.32.0/20 or 10.10.64.0/18.  These private addresses will be mapped to a public IP in the 129.67.116.0/22 netblock by the use of dynamic PAT.

Further details are available on the OUCS VPN page.
