That's about it. In addition, some ISPs make sure you cannot change the resolver advertised on DHCP, and that your own IP is routed via the Internet and back (so local requests are slow as hell), both of which can be hacked around by running your own router behind the ISP's modem/router. Of course, the real solution to the problem is to find a decent ISP, like a non-profit from FFDN.org federation. Then you have "real" internet and no worries for selfhosting.
