how to bind archiva to a ip?

[Gong Phil]

My server has 2 ip, one inner and one outer, we just don't want the
people not in our company to access the archiva, so we want to bind
the archiva to the inner ip. It really confused me for one day, I
tried to search the answer in google, but nothing can help, I just
 find out jetty it self can do it by config it in jetty.xml, but
 archiva seems not provide such config file, could anybody help me please?
