Thanks for the reply's guys.
I need to setup 2 machine's to use as a pf + carp firewall by august. My understanding is that 4.1-current has solved the axe and uberry problems and that will go into 4.2-stable. I don't know if it's a good idea to install 4.1-current on a production firewall and it looks like it's going to be difficult to get 4.1-stable to run on it. Any suggestions on what to do? If necessary I could provide access to the machine for a developer to try things out if this will help. Doros
