This needs to be a static NAT (i.e. a one-to-one relationship external to
internal). Your NAT rules need to translate the external address request
to the internal address. You also need to associate the firewall's
external interface MAC with the jabber server's NAT'd address. This is the
only way the firewall will respond to an arp request. There also needs to
be a /32 route from the external jabber server address to the internal
jabber server address.
