17.1 Legacy Series / Comunication on VLAN blocked - tcpdump unblocks it?
« on: July 18, 2017, 11:34:19 pm »
Hello Everybody,
since the last update (17.1.10 - may be I missed some) I have a wired problem on a VLAN tagged interface, which is the guest network.
Any communcation is blocked on that interface until I start tcpdump on that interface.
I am not a network expert, so I don't know what tcpdump eventually triggers.
Since in the guest network there is only a linux based wifi gateway, I can see there which pakets are send to the VLAN.
And I does not see any responses. So I wanted to see what happens at the corresponding interface of my opnsense machine.
In the moment I started there the tcpdump the replys where send.
I checked the firewall rules, if anything may be wrong, but I could not find such kind of a blocking rule.
Can anybody give me a hint? May it is a bug?
What information you will need?
Danke und Viele Grüße
Thomas
