And the biggest disadvantage is that few if any of them correcly
implements all aspects of TCP/IP when used as a TCP load balancer. They
work most of the time, but some users may experience strange problems
due to various incompabilities in TCP options or ICMP processing.

And, the code and/or silicone in these beasts are fairly young compared
to most routers or OS:es.
