Takto by sa to spravalo, keby prichodzie pakety sli cez bge0 (coz by 
mali) a odchodzie pakety sli cez bge1 (coz by tiez mali, pretoze su v 
rovnakej sieti), ale nieco by odchodzim paketom davalo ip adresu 
172.25.9.12 a nie 172.25.11.23 (co by sa asi nemalo stavat). Mozes to 
overit tcpdump-om?

Tie spojenia by IMHO mali byt smerovane na bge1.

Nemas tam este nejake NAT, alebo firewall?
