I solved this, and maybe the answer will interest the others who want to
do similar setup with uml. So what I did was to simply add +1 TAP device
to my uml, this way I got 2 interfaces, on 1 bridge.

bridge name     bridge id               STP enabled     interfaces
br0             8000.00062950d82b       no              eth0
As you see I run few other uml on this host :) but it's not a problem
because after ipsec and the 2.nd subnet got an own interface, every
problem gone.


and modification in the uml init script:
            sleep 30
            tunctl -u $USER -t tap6
            ifconfig tap6 promisc up
            brctl addif br0 tap6

It require a little time after tap5 (if this is the first interface of
the machine), but you can set lower sleep value.

The conclusion maybe that you don't use interface alias in uml for ipsec.
