you are willing to experiment, you can gradually reduce the MTU from the maximum
value of 1500 until the problem goes away. The following table describes common MTU
sizes and applications.

Set Up and Manage Dynamic DNS

Internet service providers (ISPs) assign IP addresses to identify each Internet account.
Most ISPs use dynamically assigned IP addresses. This means that the IP address can
change at any time. You can use the IP address to access your network remotely, but
most people do not know what their IP address is or when this address changes.
To make it easier to connect when you use OpenVPN, you can get a free account with
a Dynamic DNS service that lets you use a domain name to access your home network.
To use this account, you must set up the router to use Dynamic DNS. Then the router
notifies the Dynamic DNS service provider whenever its IP address changes. When you
access your Dynamic DNS account, the service finds the current IP address of your home
network and automatically connects you.
