i don't know if this is related to Debian or not however as bridging of the interface is involve in this question i hope you guys will not mind.
i have a KVM visualization server and i want the inside hosts to control via UFW. i some i add a below line in before.rule file -I FORWARD -m physdev --physdev-is-bridged -j ACCEPT which allowed all the traffic from inside out in firewall language "anywhere to anywhere." now regardless of any rule by traffic is going though the interfaces. whatever i apply as block i does not apply. to any host or to any ip. can you guyz please guide me what is happening. am i making mistake in bridging or ufw btw, my UFW config files are almost default nothing has changed. Thanks, MYK
