Maybe I'm wrong, but usually you perform NAT on the external interface (in your case it looks to be xl0). You might also want to read the FAQ on how to do NAT properly. Based on your description (which is a bit unclear so maybe I'm wrong) it doesn't sound like you ever had NAT working properly... Also, post your pf.conf and take Joachim's advice about tcpdump'ing on pflog0 and the other interfaces. Kian
