Put the server on its own DMZ network. If your router doesn't support this, you don't have a good setup for self-hosting. I did all of this for my family's software company 20 years ago. We were serious about it, too: SDSL line (good at the time!) with an SLA, natural gas standby generator, redundant hardware... never again. I spent all my time futzing with infrastructure rather than producing any business value. I did learn a ton, and that continues to be valuable (it surprises me how often I'm the only dev in the room that has experience configuring IP routing). But it's a huge time-sink, and I'd never consider doing it to save money (the amount of money saved would be marginal, at best).
