Multiple exceptions (!) with rdr in /etc/nat.conf (OpenBSD 3.0)?

[Richard Lotz <rlotz_(_at_)_u_(_dot_)_washington_(_dot_)_edu>]

I've been trying to provide multiple exceptions to the rdr command in
nat.conf.

The following works fine:

rdr on fxp1 proto tcp from ! 10.19.1.53 to any port 80 -> 10.19.1.1 port 5280

It operates as expected and redirects traffic from any IP not 10.19.1.53
on the network.  However, I have the need to allow multiple exceptions
such that it will NOT redirect the IPs I have listed.  Something like:

rdr on fxp1 proto tcp from ! 10.19.1.53 to any port 80 -> 10.19.1.1 port 5280
rdr on fxp1 proto tcp from ! 10.19.1.54 to any port 80 -> 10.19.1.1 port 5280

	or

rdr on fxp1 proto tcp from {! 10.19.1.54, ! 10.19.1.53 } to any port 80 -> \
 10.19.1.1 port 5280

However, neither syntax seems to work.  Is there something I'm over
looking or is this feature not available in 3.0's pf implementation?
When looking at the CVS updates to current it looks like some
modifications to pf nat syntax have been accepted, but I wasn't able to
discern specifics.  Is a solution available in current?

I couldn't find any reference/solution to this in the archives, but I
could have overlooked it.

thanks,
