docs/en/tor-doc-server.wml  28) The Tor network relies on volunteers to donate bandwidth. The more

docs/en/tor-doc-relay.wml   29) people who run relays, the faster the Tor network will be. If you have

docs/en/tor-doc-server.wml  30) at least 20 kilobytes/s each way, please help out Tor by configuring your

docs/en/tor-doc-relay.wml   31) Tor to be a relay too. We have many features that make Tor relays easy

docs/en/tor-doc-server.wml  32) and convenient, including rate limiting for bandwidth, exit policies so
docs/en/tor-doc-server.wml  33) you can limit your exposure to abuse complaints, and support for dynamic
docs/en/tor-doc-server.wml  34) IP addresses.</p>
docs/en/tor-doc-server.wml  35)

docs/en/tor-doc-server.wml  37) makes Tor users secure. <a

docs/en/tor-doc-relay.wml   60) <li>It's fine if the relay goes offline sometimes. The directories
docs/en/tor-doc-relay.wml   61) notice this quickly and stop advertising the relay. Just try to make

docs/en/tor-doc-server.wml  73) </li>

docs/en/tor-doc-relay.wml   74) <li>Your relay will passively estimate and advertise its recent
docs/en/tor-doc-relay.wml   75) bandwidth capacity, so high-bandwidth relays will attract more users than
docs/en/tor-doc-relay.wml   76) low-bandwidth ones. Therefore having low-bandwidth relays is useful too.

docs/en/tor-doc-server.wml 220) access to many popular services, but restricts some (such as port 25)

docs/en/tor-doc-server.wml 221) due to abuse potential. You might want an exit policy that is

docs/en/tor-doc-server.wml 265) changing your ORPort to 443 and your DirPort to 80. Many Tor
docs/en/tor-doc-server.wml 266) users are stuck behind firewalls that only let them browse the
