I have a 13.2 openSUSE with 3 network adapters, 1 for the local network and VNC, the other two (on one Intel (iirc) card) to build a bridge to be monitored by wireshark. Networkmanager, not wicked is running, all three network adapters are configured
I installed bridge-utils and and did the following with the two interfaces of the bridge:
ifconfig eth1 -arp promisc 0.0.0.0 up ifconfig eth2 -arp promisc 0.0.0.0 up brctl addbr br0 brctl addif br0 eth1 brctl addif br0 eth2 ifconfig br0 -arp promisc 0.0.0.0 up
with enp2s0f1 and enp2s0f0 as eth1 and eth2, respectively.
Afterwards I start wireshark on the br0 interface, but I only see one side of the communication on the net (the client site), nothing coming from the router. Switching the RJ45s does not help, so apparently both network cards are intact…
I had this setup up and running more than once in the past, dunno why it’S a problem this time. Anything like firewall blocking my bridge?
Any help highly appreciated!
