Thank you Ashwani,

Unfortunately using:
	rdr ce0 0.0.0.0/0 port 3891 -> 127.0.0.1 port 389
doesn't work.

When we attempt to connect to the virtual interface ce0:1 packets are
swallowed. The connection isn't refused, no association is returned in:
	ipnat -l
and there is certainly no response.

We're simply trying to provide a user-transparent means of switching
between
two LDAP directory instances. We figured port redirection would serve us
well and indeed, in our testing it did.

On our production machine we've been given a virtual interface to work
with
and we've encountered this problem.
