Jon Chiappetta: Lessons Learned From Working On A Multi-Year Transparent-Proxy Network-Wide Project
Over the years I’ve been trying to run a custom made transparent proxy service for most of my entire network to use automatically (zero client configuration). It first started because I did not like the general idea of a VPN server using a sub-1500 MTU setting while all of the clients on a network auto-assume a 1500 MTU themselves. In addition, instead of reading 1500 bytes at a time off of a TUN interface, you can instead read 8192 bytes off of a TCP socket at a time which you can then feed to a fast stream cipher. However, it took me quite a while to reach some stability with tracking all of the connection state types and to iron out all the issues that could arise from transparently proxying both UDP and TCP connections.
