External Access

Software or firmware updates require HTTP and HTTPS access to: repo.uc-x.org
VPN Remote Access
Remote access VPN services require access to: remote.emetrotel.org (using TCP port 1194)
IMPORTANT
The remote access server assigns virtual IP addresses ranging from 10.80.0.0 to 10.95.255.255 (10.80.0.0/12) to remote systems. To avoid IP address conflicts, do not use IP addresses in the same range for your network.
