Balance is a simple but powerful generic TCP proxy with round-robin load balancing and failover mechanisms. Its behavior can be controlled at runtime using a simple command line syntax. Balance supports IPv6 on the listening side, which makes it a very useful tool for IPv6 migration of IPv4 only services and servers.

Release Notes: A bug with hash_fold() regarding incoming IPv4 and IPv6 source addresses has been fixed. The "hash" group mechanism is now working as expected.
Release Notes: Buffering has been disabled for interactive shell I/O. A new "assign" command has been added to allow changing of the host:port assignment of a channel (only if disabled). A locking bug has been fixed.
Release Notes: A new -6 option has been added to force IPv6 bind. A patch contribution has been applied to solve a problem with ftok() on Solaris.
Release Notes: Problems with setting the IPV6_V6ONLY socket option are now handled more nicely with a syslog warning message.
Release Notes: This release compiles on systems where IPV6_V6ONLY is undefined (like some Solaris systems).
