My apology if someone has already asked in the past or there has alreay a guide posted somewhere about how to setup a VPN at home with DSL, dynamic IP address. I am new to this field and want some specific guideline on how to set a VPN solution (for experiment and possible future usage).
Be aware that there are often MTU concerns when you are using DSL. Make sure you look into each VPN solutions configuration options for MTU settings or fragmentation checks or maximum packet size. OpenVPN is very configurable in this way.
