Cannot route 2 local subnets to 1 remote subnet

[mts]

Hey guys,
I have the following problem:

site a)
interface 1 (subnet a): 10.0.0.0/24
interface 2 (subnet b): 10.0.4.0/24

site b)
interface 1 (subnet c): 10.0.10.0/24

I tried adding to phase 2 entries on site 1:
Local 10.0.0.0 -> 10.0.10.0
Local 10.0.4.0 -> 10.0.10.0

and on site 2:
Local 10.0.10.0 -> 10.0.0.0
Local 10.0.10.0 -> 10.0.4.0

Site 2 settings seem to be ok, but site 1 settings seem to be wrong (traffic selectors unacceptable)

I can also see in my firewall-log that a ping from subnet c into subnet a/b working (but not answered) but not the other way around.

Can someone help me?

thx
mts

don't know why, but suddenly it's working.
I just deleted phase 2 and recreated it...
