Probably the easiest way I can think to do this is to leave the dumpvdl2 running on your home machine all the time, and then on a remote machine or phone or whatever, have a SSH client connect to your home machine and run the multitail command to view the log. Of course, goes without saying anytime you open a incoming port to your network and forward it to another computer, it presents a security risk to your network, so that's something to keep in mind as well, and there are ways to mitigate those types of risks and everybody here will have a different opinion on how to do that, but the easiest way in my opinion, is to install openssh-server on your host machine and set it up, then connect your client devices. This might be one of those things I can't provide a quick guide to doing though, but there are SSH clients for phones. The variables in set up will come from issues like how to assign a static IP address to your home machine, how to set up a dynamic IP address if you have a dynamic IP from your ISP, how to get into your router and forward the port to that IP address, changing the default SSH port to an obscure port, how to remove the public key from the host machine once you have the key on the clients you want to be able to connect to you, etc. Lots of variables, but here is a tutorial I found, most things in it seem to still hold up.
