Guestline Products Firewall Whitelist

To enable our web-based products to operate without error, there may be occasions when specific URLs/Hosts need to be added to your firewall's whitelist / allowed URLs, generally, we recommend you do this by DNS/Domain Name - NOT by IP address, our IP address lists are prone to change over time and we cannot always communicate this information to you in a timely manner.

It may not be necessary to add all of the below, if you are having issues, we suggest you add the minimum to overcome any problems you are having. If you are unsure which of the below will fix your issue, add them all and then remove one at a time until the issue reoccurs, this will indicate the URL(s) that needs to remain in your firewall's whitelist.

Permit access to the following URLs/Hosts:

*guestline.net
*ap.guestline.net
*eu.guestline.net
*roomlynx.net
*rezlynx.net
*guestline.com
*rezlynx.org
