Can someone ELI5 me why DNS is such a fucking cancer with VPNs? My work machine uses VPNs and my home network, my server, etc, no probs whatsoever. I can ping outside all damn day. But to get DNS to work on my work pc sometimes I have to restart my home network to get DNS to work on the machine. I can’t wrap my head around that.
am not a network engineer but it’s because when your OS network stack and DNS were designed the idea of having multiple potential DNS servers wasn’t really much of a thing yet, i think. the stack isn’t really made for a multiple sources of truth scenario. it could be a number of things in your case - race conditions, override conflicts, etc.
