Funkyness w/IPF on Solaris 10?

Is there any known funkyness with IPF(the OS included version) on Solaris
10?

I just applied the latest recommended bundle, and now several applications
that I have that use NAT are acting funny.

For example, if I ssh from a box behind the NATTED interface, I get the
password prompt, but as soon as I enter my password I get
Read from remote host Connection reset by peer
Connection to closed.

If I disable/enable ipfilter then it works. If I reboot, I'm back to the
same problem. Disable/enable again fixes it.

I also play a multiplayer game that now no longer works reliably on my
NATTED network.

These applications worked just fine minutes before I applied the latest
Recommended x86 bundle.

Running: yes
Log Flags: 0 = none set
