+Access control
+==============
+
+Since faithd implements TCP relaying service, it is critical to implement
+proper access control to cope with malicious use. Bad guy may try to
+use your relay router to circumvent access controls, or may try to
+abuse your network (like sending SPAMs from IPv4 address that belong to you).
+Install IPv6 packet filter directives that would reject traffic from
+unwanted source. If you are using inetd-based setup, you may be able to
+use access control mechanisms in inetd.
+
+
Advanced configuration
======================
If you would like to restrict IPv4 destination for translation, you may
want to do the following:
- # route add -inet6 3ffe:0501:1234:ffff::123.0.0.0 -prefixlen 104 \
- -interface faith0
+ # route add -inet6 3ffe:0501:ffff:0000::123.0.0.0 -prefixlen 104 ::1
+ # route change -inet6 3ffe:0501:ffff:0000::123.0.0.0 -prefixlen 104 \
+ -ifp faith0
By this way, you can restrict IPv4 destination to 123.0.0.0/8.
-You may also want to reject packets toward 3ffe:0501:1234:ffff::/64 which
-is not in 3ffe:0501:1234:ffff::123.0.0.0/104. This will be left as excerside
+You may also want to reject packets toward 3ffe:0501:ffff:0000::/64 which
+is not in 3ffe:0501:ffff:0000::123.0.0.0/104. This will be left as excerside
for the reader.
By doing this, you will be able to provide your IPv4 web server to outside
IPv6 customers, without risks of unwanted open relays.
