VPN
VPN servers allocate IP address ranges to VPN clients and mediate DNS queries of
VPN clients. Any of these can be aected by a change to the VPN server’s IP address
or domain name. Additionally, the VPN server contains routing denitions based on IP
addresses. A change to the IP address can make those routing addresses unreachable.
Check all the VPN settings when changing the IP address of the VPN server.
Understanding IP Address or Network Identity Changes on Web and
Wiki Services
Some services are classied as web services. This means they provide the interaction,
back-end database storage, and media streaming of websites hosted on the server.
Web services include:
Web Â
MySQL Â
QTSS Â
Wiki Â
Certicates for web and wiki service Â
Generally, these services in the initial default conguration are resilient and adjust to
changes made to the IP address or the server name. However, if your web services
are customized, they might need manual conguration changes to maintain service
integrity.
Web
If you change the web server’s DNS name or IP address, you must modify the domain
name and web server aliases. You should also check the site load balancer members.
If you change the web server’s DNS name, you must modify virtual hosts that use
SSL. Virtual hosts that use SSL need new certicates. You might need to regenerate
or repurchase the certicates. Use Server Admin to import the new certicates, then
congure each virtual host’s new name and certicate.
If you change the web server’s IP addresses, use Server Admin to change any virtual
hosts that use a specic IP address. The default wild-card virtual host doesn’t need to
be modied.
For either change, if you congured Mobile Access for web (or possibly other proxy
settings), delete and recreate the proxy settings for all aected hosts.
