[FW1] FW1 V4, Citrix, Tuxedo and Netbackup




I have FW1 version 4 (SP2) running on Solaris 2.6 (105181-12).  The 
firewall has three legs:  network A is public, network D is a quasi 
DMZ populated with NT Citrix servers and network C is the private 
segment, home to Solaris servers running a database application, and 
using 10.X.X.X addressing.  NAT happens on the firewall.

I have several problems at the moment:

Every time we reload the rule base, all the Citrix sessions get cut 
off.  For every minor change, we need a formal network outage, which 
is a real pain (and is costing me sleep!).

The Citrix servers open Tuxedo sessions to the Unix servers in the C 
network using their translated addresses.  Then they try to continue 
the conversation on the Unix server's private (10.X.X.X) addresses.  
Does anyone know if Tuxedo includes the server's IP address in the 
packet freight, or have any other ideas about what might be causing 
this?

Netbackup's documentation states that it uses three ports (13720, 
13721, and 13782), but it turns out that it also uses ports in the 
range 512-1024 as well.  I had thought that if I created two TCP 
services, one >512 and one <1024, this would compile to a range 
512-1024.  However, when I look at the .pf file, the service_list is 
{<0, 65535>}, which I think means all ports.  I've obviously 
misunderstood this completely, so I'm hoping that someone can put me 
on the right track.

Back connections (notably back connections from ssh) seem to fail 
sometimes (I see drops in the logs), although the users are not seeing 
a problem.

TIA
