i've now spend half a day to find out that the default MAC-address set by u=
That was the reason for my bad network connectivity to several umls on one=
host bridged the local network to the umls over tuntap.
So if someone has ping problems to his two or more umls, try to set differe=
MAC-address for each uml:
=2E/linux eth0=3Dtuntap,tap1,FE:FD:00:00:00:01 ...
("I really verified the MAC-address of the tap devices" was the correct=20
approach, but i looked on the wrong side of the tap devices ;-)
Hope this will prevent someone like me spend to much time with this easy=20
thing. (Perhaps i got too little sleep the last days...)
