So it’s been a busy year for me personally as I have been trying my best to get setup in a new location and start some new routines with more focus placed on my health (diet and sleep and exercise). I’ve been battling some allergies including seasonal ones but if I get them under control in time I do feel much better (almost 95% of the way I used feel back in the day). I haven’t been able to post much here lately because of work and life but I plan to keep the blog alive if any new technical projects or anything interesting comes up.
One on-going project at home was my network-wide VPN tunnelling experiment via the Mac Mini which has been interesting. OpenVPN worked perfectly speed wise but I was having some performance issues with WireGuard and I believe it was due to the lower MTU required along with the fact that WG does not have similar functionality of being able to pre-fragment larger-sized packets coming in from the network clients being routed inside of the tunnel. I had a workaround with using a custom-modified version of nginx to proxy the client-side connection and start a newly-sized one on behalf of the client thus allowing the MTU to be respected directly from the server-side. It seemed to work better performance wise, however, I believe I was running into timing based connection errors potentially with expired states and sessions and processes.
So to end the year, I am trying a new project that I wrote from scratch in Python. It performs the same core functionality as what I modded into nginx for both UDP and TCP connection types. It’s multi-process via the load-balancing workaround/trick by using multiple localhost IP addresses and the core proxying recvs/sends is multi-threaded (you can set a single-threaded loop if you prefer). I will see how long this one lasts me going into the new year!
