hello good day,
i have a strange behavior which i can’t explain.
1 week ago my bridge between the zerotier remote network and my local clients, which was working until that time, stopped working.
funny is that when i take the zt interface out of bridge mode it is possible that i can ping other clients but the clients can not ping me.
here is my config:
auto ens7 iface ens7 inet manual
auto br0 iface br0 inet static address 172.20.1.2 netmask 255.255.0.0 gateway 172.20.1.1 dns-nameservers 126.96.36.199 bridge_ports ens7 ztks5qfoob bridge_fd 0 bridge_maxage 0
in the zweotier webui is allow bridging and do not assign ip on of course.
i have no idea anymore and unfortunately no log which could help me.
does anyone have an idea?
UPDATE: same situation if the zt interface is in br0 no ping or communication is possible. but tcpdump shows me arp requests and mcast/udp/mdsn packets flowing from the remote clients. even nmap tells me that my bridg is up if i do a scan.
i dindt touch the flow rules means all is accepted, did i missed some update information?
BTW. if installed a new bridged server with absolutly the same problem!
realy need a hint, so long thanks a lot!
