I was careless in typing this rule (and a bit lazy). The map rule is in
map le0 10.1.1.0/24 -> 0/32
I also had a rule:
map le0 10.1.1.0/24 -> 0/32 portmap 10000:40000
Which was first, but I have it hashed out now.
Sorry, I should have been more careful when I retyped that.
If I do an NVRAM update, I can probably set the eeprom flag to make
these unique, but I need to run Solaris for that I think.
Oh well. I don't think that's my problem though, as you say.
