While not strictly TCP/IP (but rather just IP), the iSeries does not 
have many of the advanced routing features of other OSes.  Filtering, 
masquerading, port forwarding, etc.  Of course it begs the question: 
does the iSeries really need those things?  It doesn't bother me - use a 
router for that stuff.

However, the performance of TCP/IP on iSeries doesn't seem too good. 
But without firm benchmarks, it's hard to know.  Is it the IP stack that 
is slow, or is the system generally slow?  I base this simply on the 
fact that my iSeries doesn't push traffic onto the wire as quickly as 
some of my other systems as measured by watching a clock.
