Okay sorry for the delay, but I was (and in fact still am) very busy with real 
life these days. Will hopefully resume to full working speed soon.

Nontheless, I finally found some time to rig a test-setup for this ruleset 
with two Soekris boxes. Unfortunately I wasn't able to see any problem. No 
hang, no stalling, nothing! Can you please try to get more information about 
the problem in your setup?

I need to know what kind of "hang" it is. Deadlock, lifelock, etc? Try to 
break into the debugger via serial console or Crtl + ALt + Esc etc. I cannot 
reproduce it, sorry.

Does anybody successfully run more than one uplink in this way? What hardware 
do you have?

Same question to Łukasz, what kind of box is this? Are we looking at an SMP

I really need some definite description of the problem. "It seems to hang" is 
way too imprecise, sorry.
