As I recall, that's typically the anonymous port range that most 
implementations use when the socket isn't bound to a specific local 
port.  You can see the code where the wanboot program does its 
connections at:

http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/common/net/wanboot/boot_http.c#tcp_connect

Seems like an awfully tight firewall configuration that would get in the 
way of other normal things, too.

That'll be complicated, because there are multiple implementations 
involved: the OBP's http client to download wanboot, and then the 
wanboot program itself.  The latter is what's in OpenSolaris, and you or 
anyone else could submit a fix, but the OBP's obviously done by the 
server hardware guys and the time to get RFE's implemented there tends 
to be very long.  I don't mean this to be discouraging, just want to be 
honest about the situation.

One workaround you might investigate is to use an http proxy which is 
outside the firewall for the wanboot clients to talk to and then you 
could just open up the firewall for it, though I doubt that would have a 
particularly better security risk profile in reality.
