Router Configurations

Make sure that the Watchguard firewall has the latest firmware version applied to it. Some older firmware versions do not have the ability to add the FQDN aliases without it we are unable to optimize the device for Weave traffic.

Please, be sure to use the WatchGuard sizing tool (available here)when installing Weave for an office. We have seen many cases were the firewall is not sized correctly and causes call quality issues and dropped calls.
