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 188.8.131.52/27.
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 184.108.40.206/22 netblock by the use of dynamic PAT.
Further details are available on the OUCS VPN page.
