this doesn't look like you can ping the address just fine... did I miss
something?  You mean from the machine with 2 nics you can ping both of
them, but from another machine you can't?

How about some setup details.  Switch? hub? crossover cables?  If you're
using a switch with lights, are they all showing a link status?  What ip
address is the other machine you're trying from - 172.16.30.25?  And to
ask the obvious (in my experience this is the biggest cause of problems)
are the cables and connections ok?  Can you prove it? (eg, "I just
bought it" isn't good enough!)

What happens when you disable eth0, and 'ping -b 172.16.0.255'?

What happens when you put a crossover cable between the two nics, put
their ip addresses on the same subnet, and
'ping -I <address1> <address2>'?

Hope this gives you some ideas to chase,
