Please include your ifconfig(8) output next time. That seems to be
where the problem lies.
It looks like you have the xl0 interface configured as,
# ifconfig xl0 inet 10.0.0.2 netmask 0xffffff00
But then you also have ep0 assigned 10.0.0.138.
Now, clearly, the xl0 and ep0 interfaces are on different local
networks, yet ep0 has an address which lies on xl0's local net. You
should not do that.
All you need to do is put xl0 and ep0 on different nets. Since you
have the whole 10/8 space to play with, you could put 10.0.1.0/24 on
one and 10.0.0.0/24 on the other. Or you could cut the one you are
using in two and just give both netmasks of 0xffffff80 and not change
any addresses.
